On what information is this belief founded?  Regardless, why should
these problems be "solved" by a userspace GUI app?

(If your laptop is getting too hot because your CPU is running at a high
frequency too often, it's probably because the kernel or SMC chip or
whatever is doing a poor job of controlling your fan.  Putting a band
aid on the problem by throttling the CPU is not the solution.)

Displaying the current freq could be nice.
