An alternate perspective:
I’d go nuts if track heights were changed inside closed folders! I keep tracks grouped in folders depending on what they’re being used for. Track height is often part of that setup. When I resize a closed folder, the view’s the way I set it up… or last left it. No surprises next time I open them up.
I figure that’s part of the purpose of folder tracks to begin with-- that’s how it works for me, anyway.
What I really wish is that that sort of control could be part of workspaces. That would help the OP, as well…
