Frequently Asked Questions (FAQ):
Q - Do the settings I set with govnah "stick" or persist across reboots?
A - Yes, taping a profile will do it. (as of v0.4.0)
Q - Why doesn't govnah display my devices temperature?
A - This feature only works with kernels that have the CPU Temperature patch applied.
Q - Why are the icons in the App Catalog flashing?
A - This happens when govnah changes its icon in the launcher, which it does relatively often. If it annoys you, you can disable it in the preferences. (as of v0.2.5)
Q - Why won't the ondemand governor obey my min_freq setting?
A - This is a known kernel bug. NOT a problem with govnah. Apparently you can trick the kernel to staying above 125mhz by setting powersave bias to 1. (Reference)

A - No. Once you apply the settings they're set untill your next reboot. You don't need to keep govnah open.
