I wasn't going to add any more features but here we are:
- added Client Visibility configuration; you can now hide clients (audio/MIDI nodes and devices in Audio, MIDI and Graph tabs) and this configuration is persistent
- added Other Settings to adjust window sizes, font size in pw-top tab and connection area width (accessible under version number menu)
- improved selection cascading in Graph; auto-selection should not cascade beyond the nearest connected client
- corrected nomenclature in some places
