It would be very useful when reusing parts of existing track to another project. For example, midi is edited or replaced in session. So changes should be automatically applied to to clips in arrangement view. However, it might be difficult task to do and take a long time in order to implement this. Now in Ableton session view and arrangement clips are completely separate things. Modifying one doesn’t affect another. It’s the biggest problem I think.

I second that. It often happens that you want to change a loop during arranging. Now you have to change every single one of that loop in the
arrangement view. A solution to this would be to put a loop from start to finish of your song and then mute the parts of the loop where
you don't want it to play, but that's not possible atm. I think Logic is able to do that, but I'd rather stick to Live.

yes, ableton should have linked clip or unlinked clip between arrangement and session
