HTML Support?

I know im probbably nagging for features now, but could we please have html support too? i know you have bbcode so if possible it had a special tag such as:
[html]<a href=”>lol pictures</a>[/html] (thats a bad example because you can use [url] for that but for example, for special embed codes like forum signatures or videos that arent on the supported list, but are embedable. Do you think its a good idea?
Oh and i have already tried, html code doesnt work.
