Currently automation tracks are not getting adjusted by flatten arranger-tracks, when they are locked..
There should be an option in the dialog or menu to use flatten on project AND the locked automation tracks getting adjusted too.
Technically it just doesn’t make sense for the sake of workflow, to unlock every automation track to flatten the tracks accuratly - but it’s currently the only option.
I don’t want to renounce on locking my automation tracks just to be able to accuratly flatten automation tracks with it.
