There are some points that should/could be improved when configuring Shortcuts (Options -> Toolbars/Menus):
Handling of modifier keys
When I just press a modifier key and release it again, the Shortcut is changed (e.g. "Ctrl+STRG", "Shift+UMSCHALT", 'Alt+ALT"). This might have to do with the fact that my system language is German.
Tab cannot be used
I managed to overwrite Editor/Tab and could not change it back to Tab even with "Use navigation keys as shortcuts". "Reset current" works though, so it is not a problem unless someone would like to assign it to some other action...
"Conflict" not updated with "Use navigation keys as shortcuts"
When the checkbox is selected, the conflict marker does not change when a conflict occurs/is resolved.
"Reset current" does not reset "Conflict"
If there is a Conflict, the marker does not go away if the conflict is resolved by "Reset current".
List does not resize with Options window
This is a problem with several options, but it already works with some (Search Rules, Roles and Editions, ...)
