Is the code surrounding the classic plugin menu scary / locked? Because when I saw the chromium browser right click window after the chromium add track and start screen where you are apparently able to bolt fresh code on the side of SONAR and appear to be steering clear of extending existing classic menu styles. Just guessing at what I see.
You know I have asked to be able to right click on fx wherever they be seen and send it to a particular plugin layout & layout folder. Rather than the cumbersome methods such as plugin manager if you happen to really like a new plug.
Frankly I don't really care if that was via a chromium window so much but I fear a reluctance to extend exiting menu structure maybe why we don't have what we want, and is logical.
What we have been given this August is nice little bone to chew though.
