Add collapse / decollapse buttons

[Markus]

NINA 2.0 HF1 BETA017

It would be helpful to implement an “inflate / deflate” button on all locations where you can minimize/maximize sections, e.g.:

• in the advanced sequencer main window and on the right side with all the templates and so an: in the moment you have to minimize each section manually
