I've been pretty happy with StickyGridHeaders for a while so, though there are a couple of outstanding issues, I have decided the current state is good enough for a stable release. Right now, in version 1.0, StickyGridHeaders provides a simple, easy to use, GridView with stickable section headers and a few configuration options. The next major release will include the headers in the view hierarchy, through some method, allowing for true interactive headers with buttons, check boxes, and things. I originally wanted to have this done now, but I am presently too busy working on Otago PsyAn Lab.
