Exploring science labs until z-levels

science labs are very hard to explore. the underground mapper does not function yet and wont until z-levels are in. the new layout of science labs are cool, but its very tricky to walk around. i found it very frustrating. does anyone have any suggestions of what we can add to the game to make it easier to explore until z-levles are done? something simple.

id also like the option to go back to original science lab layout if possible until z-levels. the straight lines are easier to navigate. i get bored trying to find my way around without some sort of mapper in the new layout. though the new layout is very cool.
