remap the floating button

[retroflexivity]

Is your feature request related to a problem? Please describe.
the floating button in tg is, well, quite useless. few people create new groups/channels regularly, and new dms are accessible through search or contact list. but floating buttons are cool because they are just under the thumb, so it's a waste

Describe the solution you'd like
a setting to remap the button. a great option would be search, as it is used much more commonly but the search button is hardly accessible. also saved messages, calls, mb switch users, anything
