[jitter] cv.jit.features question

hello,

I am looking for a .help patch that I came across a few weeks ago but cannot locate it now, maybe it is depreciated in the 1.6b bundle.

The patch was using the features2track object and a polling method, every 2000ms the object would realign the features being tracked within a bounding box automatically. I am also trying to incorporate the useroi function (box) with features2track rather than simple clicking and creating the boundary, I need to click and drag. ughh. 

Any help on this would be great, 
ty
