I'd like to see alarms with pre-set time intervals (1h, 2h, 1d, 1week, etc.) added to Joplin. This way entry is (in many cases) significantly faster than picking a date and time with your pointer, or typing date and time. Important to make such alarms persistent, in case the alarm falls into the "do not disturb" period.
I couldn't 't find a related request for Joplin posted before. Sorry if I missed it.
