Show upload success message & show at top of list not bottom (or integrate alphabetically)

[davelab6]

I tested the plugin today and it works perfectly for me; however the UX had a few 'missing stairs'

• [ ] it should automatically get a token when it starts, so this isn't a manual step;
• [ ] it should provide a success/failure message after dropping a local TTF and clicking upload;
• [ ] the uploaded font is at the very bottom of the family list, instead it should be added to the top as a convenience, or integrated into the alphabetically sorted list.
