Hi! Admittedly I've only just started using Realtime Board so it may be a little early for me to start suggesting new ideas, but a program like this one is actually something that I have been looking for for a long time so I've had ample hours to think of 'dream features' for my ideal organisational program.
1: Resizing an object in a group pushes other objects within the group out of the way.
I'm currently using Realtime Board to organise large adjacent lists and text boxes into coherent groups, however, sometimes I need to go back in to amend something. This usually means that I then have to go back out and adjust every box within the group.
I thought that it would be kind of neat to have a feature in which other objects within a group shift seamlessly out of the way of the object being scaled.
2: Pressure sensitive drawing.
Having free-form drawing on an infinite canvas in perhaps the greatest organisational program out there? Amazing. You know what would make it even more amazing? Line thickness responding to the pressure of a compatible stylus.
This is more of a luxury if anything. Like many people, I use a Wacom tablet a lot for creative work. I think that having this extra dimension to working with drawing in Realtime Board would improve the tactility of the app tenfold. I'm not sure how hard this would be to implement but I know that there are other whiteboard apps out there that use this! Microsoft's new 'Whiteboard' app does, I believe.
Anywho! Just a few ideas that popped into my head that I thought I'd share. Thank you for the app, and keep up the incredible work!
