now i get an error that the moniker 'lol' already exists (because the previous one is still there) how do i remove a moniker? And can i rename the asset and use the same 'color' to connect to the same asset under a different name?

Edit: something else i'm curious about: does this client use the same 'protocol' to color the coins as the website coinprism? or are those two incompatible? I kinda like the broader definition options on coinprism, but i absolutely hate the fact that it uses a centralised webwallet. :p
