adaptive feed enable disable and indication from halui

hi,
I was hoping to enable and disable adaptive-feed from halui but could not find a way to do that. I was hoping for some help on modifying halui.cc so adaptive feed can be directly changed from the hal layer via a panel button. It would be good to have an indication also of the current status of adaptive-feed from halui. 

Currently adaptive-feed can be modified via Gcode M52 P1 and P0. It can also be changed from the linuxcnc python module via the command channel which makes me believe that it should be changeable from halui.cc too.

I mean one easy way  to do this would be to make a python user component that imports the linuxcnc module and will check the halui status from the stat channel and update on a pin and set it from the command channel via monitoring a couple hal pins for changes.

However, I feel halui is the appropriate place to put pins for operating the machine from the machine panel.
