I've added this to our feature request list. I'll be sure to let you know if/when we're able to implement it in a future version

Thanks!

We've released TrayStatus 3.0 Beta 1, and we've added CPU and Memory indicators, as well as the ability to add indicators for any Windows Performance Counter

You can grab the beta here if you'd like to try it out: https://www.traystatus.com/Download/Beta/

Thanks!
