Also your current click to toggle is inconsistent with regular PM.
In PM if you click a folder, the images pop up. If you want 2 folders open at the same time, you right click and choose Open in Current Contact sheet. You can keep doing this to open more folders if you want.
But when you are done looking at 1 or more folders and then click on a new folder, the old folders are automatically DE-SELECTED which is the expected behavior.
In Beta 7 catalog, its the opposite. If I look at keyword or several keywords then click on a new keyword the old keywords are still selected and now I have a mess. When I am done looking at one or more keywords and click a new keyword I want and expect, from many years of doing this, the old selection to go away. I don't want to add to the selection.
I really need you to change this new toggle method. Please.
Edit:
Just saw your last reply. Fine, if a preference will allow normal behavior that's great. I really cannot live with the current setup, it is inconsistent with how windows works and how all other software I use works.
