Earlier I worked on a button that would play an audio on a !command. I then organized my audio files and moved them around from its original file location. Took me some time to realize my organizing meant there wasn't a file to be played anymore! Some pop-up or notification that a file does not exist would be nice to have!
I imagine something similar to OBS, where if a source file is moved you get a pop-up at startup. Or perhaps a red box if a path for a file doesn't exist.
