note to forum admins/moderators: i saw thats this was talk about the launcher, but feel free to move it into the right section should it not be.
these are some possible additons that could be added to the technic launcher (you can put some in here too!) :
Statistics (how many are playing now, times downloaded etc).
Patch Notes
abillity in future to add moppacks manually
choice between TMI and NEI
Time (it could happen)
more offline mode features (name changer etc).
manual RAM slider (like a slider to increase/decrease RAM used
these are all i could think of, feel free to post some and i will add them to list!
