Didn't SE say something about implementing something like the /l1, /l2 etc.... but they just said it wasn't at the top of their list at the moment...

Personally I think this is something that has been needed since release a year ago, goes hand in hand with needing mail boxes, and needing LS admin rights to kick/add people without them being on and standing right in front of you etc...

It's annoying to be crafting and have someone ask a question, have to stop crafting cancel out, change shells answer the question, and then have to do it all again when having to flip back again if they ask another one. I usually get annoyed and switch to /tell's which means I just get spammed with those.

Multi-LS chat without changing pearl's is needed within the game.
