Couple of suggestions, mainly focused around torches!
Firstly, having a spectral variation of wall torches could be really cool and can mean that you don't have to worry about how mixing wall torches and spectral torches would look like, as well as having another option for the more spooky maps.
Secondly, having the option to have torches that aren't able to be grappled to would be appreciated, especially for maps which are using wall torches as just a decoration and don't want it messing with their puzzles (and the option being there would also tell makers that torches can be grappled to in the first place)
