Introducing the new Extensions menu on the toolbar

I'm not a heavy extension user by any means, but the few that I have, I like to keep handy, but out of view. I like a clean toolbar. I keep Favourites, History & Collections on the tool bar because I use them regularly. My extensions, I just want them in the background doing their job. What I don't currently like about the new mini Extensions manager, is that if I turn it off, all extensions appear on the tool bar, with no option to move them to the menu. That option is greyed out - so will it be coming as the feature is developed? Hope so. Conversely, if I turn on the Extensions manager, I can hide the extensions themselves, but I'm forced to have the Extensions button on the tool bar. It's a strong preference of mine to have the choice of what appears on the toolbar (it's MY toolbar, after all). The current iteration of the Extensions manager is ok thinking, but I think that there should be the option to NOT show the Extensions button, AND NOT show the extensions. I know it's one button instead (in my case, 7), but I just want my regular 'go-to' buttons showing on the toolbar.
