@amandab – Wow, that looks great. Nicely done. Seems there would be interest in an add-on that does something similar…
I’ve also been looking into ways to condense fields in the post edit screens, particularly number fields (which rarely need the full width). One idea is a “columns” field which, like the tab field, finds the fields proceeding it and wraps them in a specified number of columns (field option).
