I would love this for Windows. I've missed a Windows client since Trillian/Pidgin couldn't keep up with proprietary features, and Facebook discontinued its own messenger application.

I found out about Goofy a couple of months ago and when I'm at my desk, I don't have to use my phone at all for messaging (except for whatsapp).

Now I'd wish someone would do the same for Gmail chat / Hangouts, or maybe a way to combine all the webviews into one ;)

Hangouts new chrome extension, the one with float circles, it's pretty good, and works on Linux.

Unfortunately it doesn't work well on OS X and still requires me to run Chrome in background next to the Firefox leading to alot of annoying horrible window switching issues (for some reason chrome apps tend to get stuck in background when alt-tabbing, sometimes it just hangs, burns alot of memory for a really simple interface....)

All those "web apps" that were meant to be coming to the desktop and the flurry of excitement when browsers started adding the ability to add shortcuts on the desktop to a "web app" seems to have died down, and with good reason I think! Some people don't want to be sat with a browser open all day. Given that browsers are turning into mini-OSes themselves, it's irritating as they don't fit into the OS window management system easily (like awkward popups/alerts).

Whatsapp has a web client.

I saw this, but from what I understand it was only if you had an Android phone, and it needed to be beside you the whole time while it procesed the messages for you in the background?

Not beside you, just online, but yes.

Awesome, thanks! I was just looking for something like this today! :)
