Since I'll often tab away when queueing (due to 4+ minute waits), it would be nice if the title could be changed when you enter a match. e.g. from "Card Hunter" to "Card Hunter (!!!)" This would require a simply Flash -> browser notification, with a hook in the html page to change the title. Here's a simple example/explanation from Adobe that you could copy-paste and tweak to make it work: Flash External API
That is a good idea, and in fact for a while the game even did that. At least, it did for the right browsers, in the right phases of the moon, when it didn't just cause the browser to crash. Unfortunately that last issue meant we had to take it out.
aye, the Battle joined thingy never did worked. Instead of flash -> browser, perhaps consider a jquery flashing tab instead ?
