Quote1.1.4 - compatible with the Minecraft 1.6 launcher, supports all Minecraft versions downloaded by the new launcher. Added Mojang server status check with fancy lights and tooltips. Added support for multiple accounts. Added option "Close after login". Added support for coremods, similar to the External Mods. Fixed external mod handling, mod activation and deactivation is done correctly now. Updated Forge support, mods are corectly reactivated after Forge has finished loading the mods. Fixed crash when parsing configuration entries ending with "\\". Updated news feeds, added Mojang news.
Multi-account support might be of interest to those that share computers with Family.
I use Magic Launcher, I've updated to 1.1.4, I have multiple accounts on computers shared by family members. I still prefer to keep each person's Minecraft installation sandboxed in its own folder :) See: http://forums.righteouswrath.com/index.php/topic,9200.msg66582.html#msg66582
