Disabling this mode while in fullscreen on MacOS then exits fullscreen on the app. This surely shouldn't be by design since I don't see the relation between the two.

It would also be very useful to have a keyboard shortcut for enabling/disabling FRM, especially on MacOS, where there are now two menu bars fighting for dominance when one move the cursor to the top of the window, making it difficult and aggravating to disable the calming and attention-focusing FRM.

See this image for demonstration of the narrow gap between the two menu bars necessary to hover over in order to select the Zotero bar.
