RDM does not update its data when changed in System Preferences or the number or orientation of displays changes

[purrloftruth]

Right now, if I plug in or unplug a display, or change a resolution or orientation of a display using another tool, I need to restart RDM for it to show that new data. It would be great if it detected these changes and showed them automatically.

usr-sse2@d20ee34 seems to implement this functionality, so might be a good place to start (maybe try to get @usr-sse2 to do a pull request?).

Ok, I’ll do a pull request tomorrow (UTC+3)
