Dear Michael,
Are you going to update this extension to TB 60.3.1? Probably I did a stupid thing, but I increased add-on maxVersion>100.* manually and now it works at first sight apart from Font Size option (in pints). I use it continuously many times a day and really miss the option!
I read in Toolbar Buttons section that you "don't have time right now". It's a pity. May be this add-on update does not need much time to correct it? I hope. Thank you for useful apps!
Glad to know that you are here and reading that.
