Roadmap:
Necessary:
TODO: Add a viewport # indicator for the window list for accesiblity reasons difficulty: hard
TODO: Add configuration for menu icon size difficulty: easy
TODO: Add toggle of tearables difficulty: easy
TODO: Add a sane icon dialog difficulty: medium-hard
For fun, might not implement:
TODO: Add ability to call up menus from the menu.xml file by name, if this is really, really needed or requested
