Added the Faceset menu, which is a new feature of Blender 2.83.
If the version of Blender is Blender 2.83 or later, the menu will be displayed automatically.
In the operator’s menu, replace the function similar to the new function built in Blender 2.82.
Blender built-in functions operate more lightly and more stably than add-on built-in functions.

External add-on menus are now automatically judged and displayed
Therefore, the checkbox for using external add-ons in add-on settings has been removed.
Since the mask save function of this add-on uses vertex groups, multi-resolution information that cannot be saved in vertex groups cannot be saved.
Probably not possible unless multi-reso mask data storage is officially supported.
I was reinstalling addons today, after a crash, and noticed that your Mask Tools addon (for sculpting) and Wayward Art Company’ Mask Tools (for texturing) https://www.blendermarket.com/products/mask-tools overwrite each other.
I’ve notified them too, so maybe you can figure something out or not, (It’s not such a common occurrrence, to have both, plus this not being a bug per se, to warrant triage, I don’t know).
In the meantime, I’ll try to edit the code and directory of one or the other.
