The reason it was not added is this. LiteStep as a whole is multi-monitor enabled. Themes that do not work on multiple monitors are coding errors/decisions made by the themer for that theme. Normally this falls in the error side of things. So you will have a lot of themers post "multi-monitor compliant" themes that don't really work. Its an easy fix to do and with the low amount of multi-mon users the addition didn't seem to be the best course of action.

btw...this belongs in the Site section...not the general section.
