Preferences is a tabbable, a leftover artifact of when it was, in fact, intended to be a tabbable. Rather than
re-engineer this right now, add a key event handler so that Primary-w works for this just like other dialogs
* Shorten long labels
Those increase the x-offset for the data table column on the right.
* Shorten some long ComboBox texts
* Reduce min. slider controller width
* Tag some long labels and dropdowns that are currently the bottleneck
* Split "Signal Flow" pages to reduce height requirement
-> Signal Flow & -> Solo/Monitoring
The latter is just control logic, no signal flow changes.
* Group CPU/FPU performance Options
* Move Region-Analysis to Metering (it is not performance related)
* moved some wrongly-parented items into a more sensible location
(import & export options for example)
* broke some busy pages into separate sub-tabs: Size+Scale,
MIDI Port configuration, Timecode Generators
* added "Performance" tab to consolidate some of the tweakier prefs
* moved the order of tabs around so the "indented" ones were not
so intermixed with the non-indented ones
* Show Treeview again if it was hidden
* Hide heading(s) and table when no ports are available
* Fix memory leak, unmanaged OptionEditorHeading
* remove unused members
This is used with string_compose ("detach-%1") etc,
and "preferences" may be translated by gtk or 3rd party translations
(Ardour itself only has upper-case "Preferences" as translatable
string)
Actions for hide/show/attach/detach tabbables use hard-coded names which are not
translated. Using Tabbable/WindowProxy::name() to lookup the action will fail,
since the name can be translated. This changes just removes the option to not
provide a menu-name when creating these objects, and uses the name menu-name
when looking up an action by name
Man new users drag/drop files onto the canvas without being aware
that Ardour only references external files. This can break sessions
when those files [re]moved.
