Copy Categories from one photo to another

[unqltango]

I'd like the ability to copy/paste Categories from one photo to another. It happens regularly that I'd like to use the same (or almost the same) Categories on a photo that I used on an earlier one, but I have to do all the selections manually again.

(What I do as a workaround atm is that I select both photos and I open up all the Categories and click on the ones with the black rectangles)

How I vision it:
- I select multiple photos.
- I press the "Copy Categories" hotkey.
- I select another photo or photos.
- I press the "Paste Categories" hotkey.
- Magic happens. Duplicated Categories are not copied.

It is easier to use category sets for that. Select both photos. In section assigned the assigned categories will be displayed. They appear bold for categories that are currently assigned to all selected photos and italic when they are assigned to at least one but not all selected files. Now you can simply click on the desired categories. Make them bold to assign them to all selected files. To have them written into the database and reflect the changes you have to select a new picture.
