Solving the lack of documentation

[psychoslave]

Hello,

First thank you for this extension, it seems very nice.

I fail however to find how to use it effectively. It would be great to have more documentation, especially:

• a section explaining what each icon at the top are for. The three first are most likely "add", "synchronize with server" and "parametrize". However I fail to grasp the meaning of the four others.
• how to filter by arbitrary tag: the extension seems to randomly takes three of them, but I see no obvious way to select for any other tag
• how to pop up the menu with a keyboard shortcut

The two later might be non-existent features, in which case I'll gladly open two other issues for requesting them

Thanks again for the work so far.
