I have started working on tabs.
I like your idea about having two or more conversation windows in one tab.
I don't know about blinking...
It is possible but it's a bit hard...
I dont think windows provides me an API to know if a window is flashing...
And if it did, I would have to check every once a while all the open conversation windows to see if one of them is flashing which would slow down your system...
Actually, I have something in my mind to do this, but I'll check it later...
Let me finish the tabs first
Making a plugin...?
Well, I'm making it currently as a standalone program because making a plugin would be kinda pointless at this time (compiling to see if works etc...)
But I'll see in the future about making it a plugin...
Anyway, I'll see what I can do
The bad thing is that I also got some homework to do (they are not much) but my parents I believe will start to say do your homework, do your homework!
The good thing is that schools start on 10th of January
