Hello,
Actually when we open a midi clip in the editor, the start of the editor is set to the just beginning of the clip like in the picture 
, it’s not a big problem, but i often have to scroll the editor to be sure to see the “full” beginning of the clip, in my opinion leaving a small gap at the beginning like 1/4 note or 20 - 30 pixels before the clip start could help the readability.
Then when switching from big clips to small clips, the editor zoom does not change accordingly to the clip size, when jumping from a 16 bar clip to a 1/4 clip, you have to zoom a lot to adapt it correctly to the editor.
An option for automatically adapt the editor zoom level from the newly opened clip size could imo also help a bit the overall workflow.
Thanks for your reading
