MS Office Shortcut Bar Emulator Plugin

In conclusion: as I mentioned, it comes close to what you want. Maybe it would be a nice additional feature of the "Enable auto collapse" option: also collapse whenever *another* section in the menu is expanded.

OK I've added this into my todo list. In the next version this feature will be released.

Yuri:

Here's the way I hope "enhanced auto-collapse" would look to the user. First, keep the one-click-on-title option the way it is, as it tells menus "open this title's menu group". Then just add a DOUBLE-CLICK-on-title option which tells the menu "open this title's menu group AND close all other open menu groups." The "Enable Expand/Collapse" and "Auto collapse" menu entries would not need to be changed; no other command would need to be added. The double-click-on-title option would just need to be documented after it's implemented.
