A few comments on the subject of Wifi Fixer that I’ve received:

“Wifi Fixer needs a refresh”

“The design needs to holo”

“It needs to use less memory and CPU”

I agree with all of these.  The last major design refresh was done before the design guidelines at developer.android.com were available. I’m going to try to give it some project time and do a design refresh to bring Wifi Fixer into 2013, and I’ll likely clean up the code as well.
