Is there any way I can go back to the old UI?

Not only are my tables completely messed up, but also, to be fair, I didn't quite like the new design.

Hi.  That's a question for Support - which we're not;  you could try Note History for previous layouts...

Use note history to view older versions of a note

Welcome to the forums. As you've observed, tables get messed up by the new, larger default font. Options are to resize columns, or change all text to the older font (which is still a selectable option, at least for now). I don't care for the new design either, but as of now there's no option to revert.

My guess would be that Note History wouldn't help, since older versions would simply have text in tables marked as Normal Text/Default Font, and the default font would automatically be interpreted as the new default font.
