There is some regression in Geeqie 1.1 compared with 1.0:
1.) open "File > Find duplicates ..." window
2.) drag a folder, which contains a few test duplicate files, into the window
3.) select one file of a pair of dupes
4.) choose "Delete..." via right-click menu, or press Ctrl+D
5.) in the "Delete files?" dialog, choose the "Delete" button
What happens? The file gets deleted, but the "Find duplicates" window isn't updated. The file remains in the list of dupes. Similarly for the "Rename..." action. The new file name is not displayed automatically (only after rechecking manually via the "Compare by" box).
In Geeqie 1.0, after deleting the file, the corresponding entry in the "Find duplicates" window disappears automatically.
