On Mac desktop : recently (I cannot say since when, what version) ...
a) sync button does not work any more (menu command does)
b) cursor moves freely between title and note (using the arrow keys), which is often cause of inadvertently changing the title, this is very inconvenient.
Can somebody confirm, on Mac or on other desktops ?
The sync button works for me (Fedora 41 Linux).
This change was intentional and was intended as a way to quickly move keyboard focus out of the editor (which captures tab by default).
If you think it would be helpful, I could add a setting for this to the "Extra Markdown Editor Settings". (This, however, 1) requires adding a plugin 2) doesn't change the behavior in the Rich Text Editor).
