I see a lot of people comparing this to Tab Mix Plus, but they are 2 different add-ons and do totally different things.
This add-on is just as the name says, it allows you to handle multiple tabs. Like holding the Shift key & clicking on multiple tabs to move them together. (You need to release the Shift key before dragging them, unlike with moving multiple item on the desktop.)
You can also use the Ctrl key to select multiple tabs and moving them, like with items on a desktop.. you get the idea.
Tab Mix Plus does NOT allow me to select multiple tabs to move them together. I actually uninstalled TMP because it isn't what I needed.
At times, I can have over 100 tabs open at one time & I uses this add-on to arrange them together or close multiple selected tabs. I didn't get it at first too, because it took me a while to understand it. But all in all, it's a good add-on and I haven't seen any other ones that does the same things. (There probably are, I might have just missed them?)
Also there are complains about how it doesn't have Session Manager, unlike TMP. Well, I just install it separately so it really doesn't make any difference to me.
So thank you for this add-on! :)
