Improvements to mnemonics (part of that is getting rid of a lot of the pop culture references, sorry Charlie Sheen fans) are in process, but it does take a long time. Anyways, it’s coming.
I think there are British spellings for everything though, except radicals (because the way the system was built, radicals can only take one meaning - probably something we’re doing will fix this so we can add British spellings for radicals too, but there’s a lot of underlying dev and content work that has to be done still to push that update – actually, it’s connected with the mnemonics updates, come to think of it). If there’s not a British spelling, you can always email in and we’ll add it as a synonym, probably.
P.S. Hey, you guys be nice
