First, thanks for this carefully thought-out update.
Suggestion: I’ve got a fair number of menubar extensions, so usually the DEVONthink menu is occluded by the active application menu. Here’s a shot of my screen:
Can the menubar extension name were replaced by a single width symbol?
yes you can change it in the DT3 settings>sorter to a symbol
Thanks, @vinschger! This is so much better.
I’m embarrassed to reveal: I didn’t realize this menubar item was the Sorter.
You can also hold the Command key and drag menubar items to reorder or even remove them.
I “vote” or suggest that the menubar should default to a single symbol. Menubar real estate is very precious, especially on laptop screens. Pretty greedy to take 10 spots when most take a single spot. 
Welcome @mmoran
It’s not a matter of “greed”. It’s a matter of clarity. Especially as the Sorter has never been a menubar item, the initial use of the full word can help distinguish its location for users.
It’s obviously preferential after that point.
