Like bellow, quick change groups is difficult. add-on have a slow response.

Add seems to have a bug, if last tab is a new empty tab is selected, impossible to switch btw groups.

i need to clic another tab to have the possibility to switch.

Other things. Is it possible to add option to don't reload the active tab?
When filters on a site are activated, all is reset like a new visit.

1 star and it's perfect
