may be it can be done.. you mean just gang (link) mode between all edits on
video + all edits on few selectable audio tracks? so you can move them as
group AND  this group become immune to media/clip insert and immune to its
components sliding around in this mode? or something else?

yeah, I had same idea back in time, it seems! but without any code to back
my words... now at least I have some code for starting.

yes, and then try to play with new preference in  .bcast5/Cinelerra_rc:


0 is default and sets behavior as described in manual

1 (or any non-0) forces at least effect  inserts to respect armed/unarmed
state even in gang modes media and channel. (but because this is generic
code other actions also should now respect  armed/unarmed state)

there is no propagation to preferences currently, but if you or someone
else thinks such 'mode 4' can be useful I'll monkey around in code some
