Change Icon color when toggling lifemap

I think it might be a nice addition if the small icon for toggling the lifemap on and off could also toggle between white and purple depending on if the lifemap trace is turned on or off.

Sometimes I just don’t know whether it is turned on or not, or if the reason I don’t see any trace is because I am away from any traces, if it is just slow in rendering, or something else is wrong.

If that icon was always purple when it was supposed to be on, it would take away those questions.
