I got frustrated editing input overlay layouts the way I’d been doing it, so I made coreBoard, a keyboard/mouse/controller overlay with a powerful editor. One app, undo/redo, recent files. Same NohBoard file-format, so your current layouts open as-is and you can keep using them in the same OBS capture workflow.

If you’ve had the same issues, might be useful. Windows, open source.
