(i’m to lazy to read through my post so there may well be spellingerrors of the worst kind :P)
With ingame serverbrowser’s much like the ones in Quake 3 and Quake 4 you don’t get a good overview and it takes time to start the game and exit just to take a look at a server, you’ll have to do this a number of times too since there are servers wich doesn’t work for everybody.
With an external browser, in a simple Windows window:
You can chat with friends who you would like to play with on IRC, ICQ, AIM, MSN etc. when discussing serverchoic etc.
And because it’s not ingame you can have it on all the time, where ppl can contact you when you’re not playing, you’ll stay in contact with the community all the time.
Another additional feature in this program could be a simple textbox with news concerning ET:QW.
With almost all of the games I play, I use All-Seeing Eye wich is easy to use and such… The only games I don’t use an other browser than the games itself are Steam-games.
This browser doesn’t have to be like Steam - A simple serverbrowser with a chatlobby, much like IRC or something similiar and a friendslist.
