When selecting ‘FUNC’ + ‘PAGE’ to show you the track and pattern length page - I think it would be good to clearly say ’ Per Pattern’ or ‘Per Track’ to let you know which mode you are in.
I know it does this at the minute, but its kinda backwards, it says ‘func + yes = per track’
Just keep it simple and say which mode we are IN currently, not how to get to the other mode.
