Latest reviews
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
Really useful.
love it and very useful.
yayy
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.
Love the extension but not happy with the nagware window and clicking on "skip" fails to close this window.
Cool!
Thank god for this!
Handy!
Works the way I expect it to. Thanks!
Simple, effective, does exactly what it says on the tin.
I like the idea, but it opens a nagware window when you use it, and clicking on "skip" to dismiss doesn't remove it.
Love this !
FInally. Works perfectly
Thank you. Installed and it is working. No questions.
