Support mind mapping#433

The whiteboard supports mind map cards, using shortcuts such as Enter to insert cards of the same level, TAB to insert sub level cards, and automatic connection

EXACTLY, I’m super tired to use MindSpace app and again swich to Scrintal just for the mindmap creation.

MindMaps are lighting fast and compact to clarify ideas!!

the main mindjet feature I’d like is to be able to click to expand/close trees.

Trying to simulate a super simple organical mindmap of a company and with the avaliable arrows it’s just a chaos…
