In the new experimental Sidebar under Properties the Number Format (General, Date etc.)is displayed. Missing is the Format Code itself, which would be very helpful.

Sidebar screenshot from 4.4
If I understood you, that should be there from 4.3.
If I'm right, please close the bug.

What are you refering to "Category" was always in the sidebar. I mean the "Format Code" so far only available in the Format Cells under Numbers on bottom where you can change/modify the display format.
But I just discovered the "More Options.." in the header of the Format which brings you to the main formating window. So we can close the bug.
