All this add-on does is display what is already on your client, it does not do any extra request to the server, the add-on does not write anything on your computer/browser, there is no lasting effect of it ever being there, so no extra organizing possible, it just use the in-memory data that the server sent to your browser.

Note that you can actually right click the sheet header to switch rapidly between all the already opened sheets, if that helps, there are few places where you can right click (all the places with a "?" for starter), i guess i am too lazy to make a proper tutorial, sorry.
