It’s on my to-do list… but pretty far down… :(
The panel.js file need some major refactoring… but without any way to write test cases it’s very fragile… at the very least I’d like to see it use TypeScript over JavaScript… but that’s going to require someone with build mojo (not me).
On the plus side I did add decorations support! The web client now supports arrows, bridges, end bumpers and tunnels! ;-)
