--[[About this plugin
-This plugin adds the button(s) to the "Selected Images" module:
-1) Return to Previous Collection
-2) Collect on image's Folder
-3) Collect on image's Color Label(s)
-4) Collect on All (AND)
-
-It also adds 3 preferences to the lua options dialog box which allow the user to activate/deactivate the 3 "Collect on" buttons.
-
-Button Behavior:
-1) Return to Previous Collection - Will reset the collect parameters to the previously active settings
-2) Collect on image's Folder - Will change the collect parameters to be "Folder" with a value of the selected image's folder location
-3) Collect on image's Color Label(s) - Will change the collect parameter to be "Color" with a value of the selected images color labels, will apply multiple parameters with AND logic if multiple exist
-4) Collect on All (AND) - Will collect on all parameters activated by the preferences dialog, as such this button is redundant if you only have one of the two other options enabled

+
+--[[About this plugin
+This plugin adds the button(s) to the "Selected Images" module:
+1) Return to Previous Collection
+2) Collect on image's Folder
+3) Collect on image's Color Label(s)
+4) Collect on All (AND)
+
+It also adds 3 preferences to the lua options dialog box which allow the user to activate/deactivate the 3 "Collect on" buttons.
+
+Button Behavior:
+1) Return to Previous Collection - Will reset the collect parameters to the previously active settings
+2) Collect on image's Folder - Will change the collect parameters to be "Folder" with a value of the selected image's folder location
+3) Collect on image's Color Label(s) - Will change the collect parameter to be "Color" with a value of the selected images color labels, will apply multiple parameters with AND logic if multiple exist
+4) Collect on All (AND) - Will collect on all parameters activated by the preferences dialog, as such this button is redundant if you only have one of the two other options enabled

-This plugin adds the module 'HDRMerge' to darktable's lighttable view
-
----REQUIRED SOFTWARE----
-HDRMerge ver. 4.5 or greater
-
----USAGE----
-Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
- 1) Copy this file in to your 'lua/contrib' folder where all other scripts reside. 
- 2) Require this file in your luarc file, as with any other dt plug-in
-On the initial startup go to darktable settings > lua options and set your executable paths and other preferences, then restart darktable
-
-Select bracketed images and press the Run HDRMerge button. The resulting DNG will be auto-imported into darktable.
-Additional tags or style can be applied on auto import as well, if you desire.
-
-Base Options:
-Select your desired BPS (bits per sample and Embedded Preview Size. 
-
-Batch Options:
-Select if you want to run in batch mode or not
-Select the gap, in seconds, between images for auto grouping in batch mode
-
-See HDRMerge manual for further detail: http://jcelaya.github.io/hdrmerge/documentation/2014/07/11/user-manual.html
-
-Auto-import Options:
-Select a style, whether you want tags to be copied from the original, and any additional tags you desire added when the new image is auto-imported

+--[[About this Plugin
+This plugin adds the module 'HDRMerge' to darktable's lighttable view
+
+----REQUIRED SOFTWARE----
+HDRMerge ver. 4.5 or greater
+
+----USAGE----
+Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
+ 1) Copy this file in to your 'lua/contrib' folder where all other scripts reside. 
+ 2) Require this file in your luarc file, as with any other dt plug-in
+On the initial startup go to darktable settings > lua options and set your executable paths and other preferences, then restart darktable
+
+Select bracketed images and press the Run HDRMerge button. The resulting DNG will be auto-imported into darktable.
+Additional tags or style can be applied on auto import as well, if you desire.
+
+Base Options:
+Select your desired BPS (bits per sample and Embedded Preview Size. 
+
+Batch Options:
+Select if you want to run in batch mode or not
+Select the gap, in seconds, between images for auto grouping in batch mode
+
+See HDRMerge manual for further detail: http://jcelaya.github.io/hdrmerge/documentation/2014/07/11/user-manual.html
+
+Auto-import Options:
+Select a style, whether you want tags to be copied from the original, and any additional tags you desire added when the new image is auto-imported

--[[About this plugin
-This plugin adds the module "OpenInExplorer" to darktable's lighttable view.
-
----REQUIRED SOFTWARE----
-Apple macOS, Microsoft Windows or Linux
-
----USAGE----
-Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
- 1) Copy this file into your "lua/contrib" folder where all other scripts reside. 
- 2) Require this file in your luarc file, as with any other dt plug-in
-
-Select the photo(s) you wish to find in your operating system's file manager and press "show in file explorer" in the "selected images" section.
-
- Nautilus (Linux), Explorer (Windows), and Finder (macOS prior to Mojave) will open one window for each selected image at the file's location. The file name will be highlighted.
-
- On macOS Mojave and Catalina the Finder will open one window for each different directory. In these windows only the last one of the corresponding files will be highlighted (bug or feature?).
-
- Dolphin (Linux) will open one window with tabs for the different directories. All the selected images' file names are highlighted in their respective directories.
-
-As an alternative option you can choose to show the image file names as symbolic links in an arbitrary directory. Go to preferences|Lua options. This option is not available for Windows users as on Windows solely admins are allowed to create links.
-
- Pros: You do not clutter up your display with multiple windows. So there is no need to limit the number of selections.
-
- Cons: If you want to work with the files you are one step behind the original data.
-

+X-Touch Mini flexible encoder shortcuts
+
+This script will create virtual sliders that are mapped dynamically to
+the most relevant sliders for the currently focused processing module.
+Tailored modules are color zones, tone equalizer, color calibration and
+mask manager properties. The script can easily be amended for other
+devices or personal preferences. Virtual "toggle" buttons can be created
+as well, that dynamically change meaning depending on current status.
+
+USAGE
+* require this script from your main lua file
+* restart darktable
+* create shortcuts for each of the encoders on the x-touch mini
+  to a virtual slider under lua/x-touch
+  or import the following shortcutsrc file in the shortcuts dialog/preferences tab:
