Use case or problem
In order to create very clean Mindmaps/Organizational Charts in the flow of working from a central card in canvas, I sometimes wish for straight connector-lines which I can easily snap to specific angles to create a visually pleasing (symmetric) chart 
Proposed solution
Allow us to create straight connector lines, wich snap to specific angles (e.g. 30° increments) while holding down the shift key.
By the way - I love where Obsidian is heading! Great work!!!
