Hi,
The possibility to have a default type of alert.
I mean, if I prefer to have my games only with Steam key, when any price drop come and be notified by instant e-mail and brower pop-up, it would be nice to have a default type of alert, maybe create multiple type. Because, actually, I always have to uncheck the other launcher, or check something else, and it's a pain in the *ss.
And long time ago, it existed a plugin on Firefox which say, on the Steam Store page's game, when a game was in a bundle, and also his lowest price on Steam, and resellers.
