One hand use topic

Hi!

I'd like to know if anybody actually uses Samsung's features in order to help using the phone with one hand?

I myself make only use of the (not convincingly thought through) gesture which allows me to shrink the screen.

The assistant menu:
quite customisable, but much too big and slow for my taste.

Side key panel:
the other way round, quite comfortable to use, but nearly no customisation at all.

All in all I'd say lots of options, but not really thought through. What do you think?
