Simple problem, just not implemented?
Very possible.
I implemented a core set of the code, then have been adding to it on request for most of the rest of the time - driven largely by Gabriel.
It's just a very large API, and I can only sit and go through a given amount of it in one session as it starts to drive you mad after a while ;-)
(Disclaimer - it starts to drive me mad after a while... prolly why I like to mingle large modules with smaller ones as I go, to keep myself at least 5% sane).
I'll look into the ones you are having trouble with.
As for Grid Disable/Enable, it sounds like that is library specific. But I'll check it over anyway.
