[Feature] Floor navigation guides

[MrMagolor]

did you give up on em?

i feel like what i have is ALMOST where it needs to be. i think it needs icons but the icons need to be omni-directional or i need to just make the icon always face down no matter how the floor strip is oriented

easy ones:

medbay -> + sign, easy
engineering -> a wrench is not something that needs to face a certain direction.
botany -> a flower or leaf? hell if i know how to convey that as a small icon.
science -> an atom/molecule symbol. might be tough to squeeze in but i have room to expand these things a bit.
command -> a star would work fine

harder ones:

sec -> 4 shields forming an X, perhaps. or an eye? or a box with an x inside of it? if not omni-directional then a shield is fine.
evac -> 4 arrows pointing outwards from a center circle?
QM -> 4 lines in a row or something? if not omni-directional then maybe a briefcase?
mining -> mining pick i suppose would work but it would not be omni-directional.

some of these are a bit abstract so maybe i have to bite the bullet and make their icon always face downwards so players can always read them properly.

I think that having a beaker of some sort for science makes sense. Also, for QM, there could be a crate or a dollar sign.
