HELPER SCRIPTS: CSS call in user definitions

Hi John
I guess this is more of a feature request really, but as with many of the manufactures, they make heavy use of Framework. Additionally they include helper scripts that are bespoke and apply to their particular setup set.
What would be excellent, would be a user script where you could add your own objects (or copy pieces from others) the expose methods that are of significance eg
I would like a toggle fold/unfold function for my controller as its essential for my performance workflow.
As far as I can see, to do this (collapse all) requires
1. Iteration through the track list
2. If a track is foldable, fold it

and the inverse of course.

I couldnt see it in framework but is probably there…Im using it to illustrate that a user could write the extension and have css reference/import and provide a globally scoped method
ie
self.grouped_tracks_fold( true )
and with one fell swoop, elegantly manage the issue

It means too…a CSS file could be built in the same way (if it hasnt already) where the LOM repository could easily have a library reference with docs which would make it so much easier

Welcome your thoughts.
