Help for checkboxes on ui template node missing

I couldnt find a help entry for the 3 checkboxes on the ui-template node (v 1.21).
The reason i'm asking is, cause i had some changed behavior since the last update (pre 1.0) and it seems something was changed in that area...(i'm not sure, but i believe there was only 2 checkboxes)

PS: A history for the search box would also be nice...
