Hi! I'm sorry but this is something I won't be implementing. There isn't only one reason, and even though s4br0s0 has articulated most of them, there's an even more important reason for me not implemeting bubbles: I wouldn't even know where to start. I'm not really a QT coder, nor in fact an UI coder at all, so I would have to spend lots of time just to draw a simple bubble, I don't want to think about all the time I'd spend on this while there are other features I care more about. Nonetheless, if anyone is able to write such a GUI and make it so its optional, I will be merging those changes into mainstream without a doubt, but I won't be doing it myself. Sorry about that.
