Not going to reject this one since the code was there from the old versions but you should remove the timeout in disable (extension.js line 72): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#remove-main-loop-sources

@JustPerfection GLib.SOURCE_REMOVE does the thing, doesn't it?

As mentioned in the review guidelines: > You MUST remove all active main loop sources in disable(), even if the callback function will eventually return false or GLib.SOURCE_REMOVE. It's because the timeout can be called in lock screen when the extension is disabled (in racy situations or in case we have unwanted additional delay).
