Would it be possible to reload the config.txt with "c" key forcefully? 

For example:
1.  I press "c" and my config loads up hardware parameters.
2.  I go into a different application and adjust GPU power/clock/fan.
3.  If I press "c" again on the miner, it doesn't reload my settings. 

It doesn't know that hardware parameters were changed elsewhere.  My theory is pressing the "c" key reloads config.txt, compares it with the current set of parameters, then only applies parameters that have been updated.  It does not forcefully reload the entire config.txt.
