control point picker & list fixes

Hmm, you're right, maybe it should stay zoomed for a second or should return
to fit-to-screen on mb3 or so?!

Yes, exactly my thoughts. Having additional zoomed windows like PTOpenGui
would solve the problem?! My method with PTOpenGui always was:
- picking in fit_to_screen window 1
- adjusting in 100% view window 1 (if nessesairy)
- picking in fit_to_screen window 2
- adjusting in 100% view window 2 (if nessesairy)

Seems to be, that Pit likes more to work in 100% view, i prefer the
fit-to-screen variant for intial picking and 100% for adjusting?!

Using the back button should do for now what you want.

I would appriciate that too. In combination with a key to zoom/center the
actual control point pair that would work pretty comfortable?!

best, mike
