Thanks for your work on this Travis.

Sometimes, the impossible can become possible, if you're awesome!

This helps out a lot, thank you Travis Carrico !



I'm surprised that you supply a GUI while the official version doesn't!

But can you define the word "optimize" in your GUI? The command line parameter "-a" has 8 types of optimization (although unlike type 3, types 5-11 do not contain the word "optimize" in their descriptions)?

How do you go about adding your own parameters and options? I know on the regular version you just create a shortcut and add them to end of it, but how do you do it with this portable version?
