Import Preferences from MuseScore 2
It is good that if users can import preferences (including shortcut, etc.) from MuseScore 2 (2.3.2) to 3 (3.0).
Files in "MuseScore 2" (e.g. soundfonts) can also be copied automatically.
(Should I start a new issue for this request?)
You can open an issue, but realistically too much has changed - it's a major version change after all - for this to be very effective. You can of course copy, move, or link soundfonts.
I pointed my soundfonts folder to my version 2 soundfonts so I didn't have to do a bunch of copying.
