Currently, when Gwenview enters View Mode, or changes between images while in View mode, the window title in the titlebar changes to "[filename] - [width]x[height] - [zoom]% -- Gwenview". This is useful.
However, when Gwenview is in Browse Mode, the window title is just "Gwenview". Opening a 2nd Gwenview window, also in Browse Mode, sets the new window title to "Gwenview <2>". This isn't very useful, especially with multiple Gwenview windows browsing different directories.
Request that when a Gwenview window is in Browse Mode, it set its window title to the name of the current directory. For example, "vacation pics -- Gwenview". This would be similar to the behavior of e.g. Dolphin.
Yup, that's something which has been on my TODO list for a long time. The feature is kinda obvious, isn't it ;)
Confirming for now, but no promises. Setting the directory name is a good idea, but maybe we'll can come up with even more ideas (not sure yet).
A possibly relevant merge request was started @ https://invent.kde.org/graphics/gwenview/-/merge_requests/30
Fixed by Antonio Prcela with https://commits.kde.org/gwenview/cc09a2a7ad63a6ad19cbc759dbcf5eda050b66ee in Gwenview 21.04!
