- I really like this and I am only here *because* of the nagware window telling me to review it, and I'd give it 5 stars for just working perfectly if it weren't for them demanding I did so

- extension is great! Very helpful! I am only missing the possibility of assigning a custom keyboard shortcut, I'd really appreciate if you could implement this!

- This should be a standard Chrome feature.

- A) the nagware is a pain in the neck. It casts a light on 'positive' judgments. Think about that. B) I would like to be more flexible when merging windows. Not all at once, but I would like to select the ones I want to merge in one larger one. Feasible? Without nagware? Thanks.

- I like the idea, but it opens a nagware window when you use it, and clicking on "skip" to dismiss doesn't remove it.
