This avoids breaking bindings, and since the action name is generally not a part of the GUI,
really doesn't hurt anything in terms of understandability
An attempt to satisfy #8848.
Add a new action, "fork-regions-from-unselected", which unlinks all
selected MIDI regions from any unselected regions, but maintains links
within the selection, and add the new action to the region MIDI context
menu as "Unlink from unselected". Rename the existing "fork-region" action
to "fork-selected-regions", and amend the existing "Unlink from other
copies" menu item to "Unlink all selected regions" to (try to) clarify the
difference.
Attach the <Tertiary>U default key-binding to the new action: I personally
think it's generally slightly more useful (otherwise I wouldn't have
implemented it), though I'm not that fussed.
In the case that there's only one MIDI region selected, or that none of
the selected regions are mutually linked, both actions will have exactly
the same result. Ideally, we'd only show a single menu item in this case,
but that would require (a) implementing a function to check whether the
selection contains any linked regions, and (b) making the region MIDI
context sub-menu dynamically generated, so that it can change based on the
result of that function, neither of which I've tried to do yet.
Existing function select-all-tracks is now renamed select-all-visible-lanes, to match its behavior.
New function select-all-tracks will select all Tracks, as the name implies.
To maintain consistency for those users who actively used select-all-tracks,
the default shortcut ctrl+t will continue calling select-all-visible-lanes.
Duplicate the remove_unsued_region action in the Session->Cleanup menu, for discoverability.
Region list should use the same Region actions as the canvas...
OK, now resolve the change in use-cases of Region List and Source List. tentative.
Rough-in remove_selected_sources (Delete in Sources list).
Column tweaks.
