I use tags in the track names
for instance ‘#’ is for groups.
example
ctrl+alt+F+#
will bring up:
#GtrElecAll
#DrmOH
#DrmAll
#VocBG
etc
and then I’m also consistent with name tags - Drm for Drum, Voc for Vocals, Gtr for guitars, Syn for synth - etc, etc. And then are more specific subtags like ‘VocLd’ for Lead Vocal, and VocLdDbl for Lead Vocal Double.
I’ve trained myself to just be consistent with my naming, and come up with my own sort of code language to find things quickly.
That at least solves 1 and 2 for you, albeit, will require some manual organizational to stay on top of.
