This is a re-release of 2.1.12 with the module.json fixed to not break on Foundry V11.
New Feature: Popout (#16)

You can set a keybind to open it and can set it to open automatically when loading the world. It also saves its position, so it won't conflict with other windows like the Region Legend.
You don't need the original Dice Tray enabled.
Caveats
- If a chat popout is opened, the Dice Tray popout will interact with it instead of the sidebar's chat.
- The window has a big top margin because I couldn't figure out how to have the orange numbers ignore the header. Help from any CSSorcerer is welcome.
