Multiple parameters settings

[logusergithub]

Hi, thanks for the script (while I'm at it I also add the thankfulness for 'Sidebar Switch', I'm just sad I didn't discover it sooner).
Speaking about 'about:config Menu Shortcut' I'm finding it very useful especially for the ability to enter parameters at will and it seems to work fine for the default hidden options like 'letterboxing' as well (although the 'reset' entry doesn't indicate the defaut parameter in such cases).
Not strictly a request, but if in the future and in case it is feasible, it would be helpful to have these additions:

• the ability to show or not show the 'pref:' popup;
• as per the image below, the ability to create menu choices to multiple change parameters by clicking on them, parameters that a user configures itself.

Already, however, it is of great use!
