Optional Placement Grid
An optional placement grid whould be great.
I assume that many of us dont just want to use Mindmup for quickly thrown-together brainstorm layouts, but also want to make the whole thing look a bit more professional, and the ability to line up nodes properly with a grid whould be great for this.
also: please have an option or simply change how stickers and node extension change the "middle" of a node. it's incredibly frustrating when moving nodes around that, for example have a sticker, and the node then moving to a different place. likewise, when adding a sticker, since the nodes height will now be different, it often moves other nearby nodes around if they are too close.
The ability to lock the location of a node within (or without) a grid would be really, really helpful. I think that both would accomplish the same thing.
