Is this just me? If I go to edit text, the tab menu goes a bit crazy. Examples attached.

Also Ctrl+T seems to be a bit hit or miss as to when it will work for me (this is the 683 build).

Nevermind on the images of the tabs being crazy... it's all me on that one.
I get it now!

But Ctrl+T seems to be hit or miss for me still.

That looks correct to me. You are in Text Editing mode (Tabs-crazy.png). The interface changes slightly because of the editing controls being displayed. When you exit out of Text Editing mode, it will return to the way Tabs-normal.png displays.

Yeah, it finally sunk in as to the look of the tabs when editing (crazy) vs not editing (normal).
It's just me that is crazy at this point.
