A quick and easy way to visually save ideas (p4d.io)

I got frustrated with my options for writing down my ideas and exploring them, so I made my own. Nothing groundbreaking, but its a useful visual whiteboard. You can easily save ideas, connect them, as well as draw or type on notes. Check it out at p4d.io

I like it

Maybe make it less skeuomorphic and more floating-window-manager style?
