Hello,
I am running Joplin 1.2.6 on linux.
I was about to make a feature request for sorting lines within a note/todo (both of an entire note and from a selection) in the joplin editor but it seems to already be implemented.
The shortcut in the linked post is not listed in the shortcuts of my joplin version and unsurprisingly doesn't work.
I would be very grateful if someone could point me towards that feature and spare me the hassle of switching to an external editor every time I want sorted lines!
