The above might be from omins, not sure.
Just get all recommended collections.

Point every Om user to the above link ;)

No. Can't do that with binaries, as there are varying platforms.
Can't do it with source code without reimplementing something like portage.

The only option for improvment I see, would be something like a
plugin registry and/or a common way to build plugins from source.
I don't see that happening any time soon.

Strange. Never had issues there.

There's an tutorial for the last release:

It will be updated or another one added when someone gets around
to it ;)

Create a new Subpatch, set polyphony to 6. Make sure the oscillator(s)
are created polyhonic (checkbox in load dialog). For what else to
put in there, have a look at the examples.

The Om-synth project can't take care of that, it's outside of
the scope. There was a effort that died off soon, to give some
info and usage tips for a selection of plugins:
