[ESS] the R help system

I have two things which are either enhancement requests or just me not
doing the right thing. Both are related to the R help system. My
examples below are for a S4 class from package Biobase, but it should
be generally applicable.
1) S4 classes. If I do C-c C-v and try to find the help page on the
class ExpressionSet, I can get the help page if I type "ExpressionSet-
class", but not via TAB completion. If I (from the R command prompt)
type ?"ExpressionSet-class" I get a normal help page buffer, but if I
do class?ExpressionSet, the help is printed in the R buffer instead of
its own window.
2) conflicting help pages. If I have two packages, both with a help
page linking to the same term (an excellent example right now is the
Bioconductor package "affy" and the help page for image), I used to
get an annoying tcltk window popping up. It was annoying and slow, but
worked. Recently I put the following in my Rprofile
options(menu.graphics = FALSE)
If I now do ?image from an R session, the little selection menu is not
displayed at the R prompt, but rather in a separate read-only help
buffer. If I try to do C-c C-v image, the same happens.
