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 + +----REQUIRED SOFTWARE---- +NA + +----USAGE---- +Install: (see here for more detail: https://github.com/darktable-org/lua-scripts ) + 1) Copy this file in to your "lua/contrib"
