Feature Request - Other application thumbnail? Myabe Firefox?

[Tharnadar]

I don't know if it's possible, but it will be really useful if we could add other application in the thumbnail, like for example for Firefox.

Usually I navigate the internet while playing and when I go to Firefox then I use EVE O-Preview to get back to the game client, and sometimes I'm looking for firefox in the previews, but I cannot find it, then I remember then I need to look at task bar...

I hope I was clear.
Thanks
