I am not holding my breath for a change but the current functionality is also limited unless there is integration with email such as those extensions that also check dictionaries.
That said, there is also an issue with how the Tags are selected - I mentioned this a while back. With the extension you can type any word and if it appears anywhere in the Tag it will show up but in the desktop version which should be more powerful you must enter the word in the order it appears in the tag.
Example Bank
Extension --- Big Bank (found)
Desktop --- Big Bank (not found)
Desktop --- Big..... (found) *** seems as if they are using a simple index to search via the desktop and a string search in the extension.
Back to the issue - the ask is simple in that if it does not exist/create it and I the user makes a spelling mistake that creates duplicates etc so be it .... it is still far easier to work with than having to go back into the app, load the note and add the Tag
