I've been an FVD user for years but it was time to switch my dial add-on that is compatible with the new multiprocess functionality in Firefox. Firefox 57 compatibility is also a big plus at this stage in development. This dial add-on has it all. It's smooth, fast, and offers the ability to layer dials which is really nice. The cloud sync is also great and works well. I'm using it in both Firefox and Chrome across multiple windows operating systems (7 and 10). My only suggestion is to add the ability for the Main Group bar at the top to wrap as when I had a huge list of groups it wasn't able to wrap to a new line. Keep up the great work!
