I never saw any of those features in the old IRC codes of Msg+ but please correct me if I'm wrong...
If you want, you can erase them with this code
code:
strMyNewPSM = strMyNewPSM.replace(/\[c=([1-6]?\d|#[0-9A-Fa-f]{6})\](.*?)\[\/c(?:=(?:[1-6]?\d|#[0-9A-Fa-f]{6}))\]/g, "·\$$$1$2·\$")
strMyNewPSM = strMyNewPSM.replace(/\[a=(?:[1-6]?\d|#[0-9A-Fa-f]{6})\](.*?)\[\/a(?:=(?:[1-6]?\d|#[0-9A-Fa-f]{6}))\]/g, "$1")
strMyNewPSM = strMyNewPSM.replace(/^\s+/g, "");
If it finds a gradient only the starting color will be used...
