it sounds like a user error to me. furthermore, i have no clue what "adding icons to my modules" even means.

try reading some documentation thoroughly and understanding the concept of how litestep works and you will run into far less errors.

moreover, if you are unsatisfied with the theme selection (as they are boring and lack functionality as you so eloquently put it) then go out on a crazy limb and make one yourself. the only person you'll have to blame if it sucks is yourself. believe me, i blame myself all the time for my themes sucking and i find it quite easy to live with.
