Hello,
thank you for this useful plugin.
I have been using this plugin since its initial version, but approx. 6 month ago it started to hinder the functionality of the aforementioned button.
This may be beyond the scope of this extension, if it is even possible at all, but I would find it very useful if I could still use menu hotkeys (alt-F, etc.) to bring up menus, even while the menu is "hidden". I don't know if this could be done by just setting the height to 0 or something instead of hiding the menu entirely. This is how Firefox works, and I find it very useful. Just a suggestion.
