When I press Enter or Double click on a Shortcut, the shortcut list window pops… on top of the CCR window… which is on top of main calibre window… at the selected shortcut:

When I press Enter or Double click on an Action or Setting, the
CCR window is pushed behind the main calibre window and then the 'relevant' settings window is popped… easy to lose track of where one is at.
Am I right in saying the Action and especially the Settings lists themselves are incomplete, as well as the linkages to 'whatever' being sometimes erroneous, e.g.
AFAIK - there is no such feature as "Preferences->Library->Splitting", the "Check Duplicates on Copy/Move" setting is in Preferences->Adding books
Should these lists have "Under Construction" signage?
The Custom columns tab especially needs to show the current library Name/Path. But that is also true of other sections, there many other per-library features - virtual libraries, various PI settings. Have a look at metadata_db_prefs_backup.json in a library folder.
