I would be in favor of the translation one, depending on how well it does (and what service(s) it uses for translation). I think thereβs not really enough math posted on this forum to justify a whole plugin for it - usually people just write things in code, which is more useful for everyone anyway. Iβm ambivalent about the color one, I donβt know that it adds a lot, but Iβm not opposed if other people wanted it.
The only limitation here is that, plugins needs to be manually updated - itβs not a lot of work, in general just one click, but it has to be done often if we want to keep the forum up to date (and broken plugins cause headaches as well), so Iβd just want to make sure everything we install is something highly desirable / useful / stable.
