This addon is a really great concept and just what I needed, however I would rate 5 stars if there was a 'move to other window' option on the context menu of each tab. At present it's pretty slow to move multiple tabs to another window, or move a tab which is on the opposite side of the browser window to the 'Other Win' button.

Also, often, when Ieft click on the 'Other Win' button in '2 Window' mode, it swaps to the destination window and stays there, while other times it stays on the source window.

good! it is that i need! i don't understand why is not in default feature browser.

Does what I wanted! Would be nice if I could name my windows so that I could easier recognize them.

Edit:
Thank you! I am using the new naming feature now and so far it is really helpful. Some other extensions use a window's current tab's title as the window's name but I like naming the windows better. This is probably my favorite way of switching windows currently and it works really well.
