Razor Designer

Drag-and-drop UI editor for S&Box

A gorgeous canvas to work on

Every property you'd ever want to change or not change on any UI element you could ever want in one Inspector column

Pseudoclasses - see what happens when you hover or activate a button live on the canvas preview!
Hotkeys - the usual Ctrl+O to open, Ctrl+S to save, you get the idea there are tooltips if you forget them
Pan / Zoom with the mouse wheel . Click it to pan, scroll it to zoom. Easy enough?
Shift dragging - locks to X/Y axis
Alt dragging - resize here and there 
C# variable configuration...yeah i'm excited too it's cool
Play with the arrow keys to nudge stuff around it's awesome.
s&box themed templates ready for you to use! you're lucky i'm so generous...
performance is great (i checked)

Stuff it don't got: (yet)
