For example, I've complained here (because the forum feedback system constantly rejects my attempts to submit as I am unauthorized) about the weird double post thing that happens to some of us that doesn't happen in the 6/7 or 8 forum...as you can see...oh wait...still borked.
More seriously, I really do love Notes; I've made a good living doing design work for more than 20 years. The platform is flexible, easy to use, and offers lots of built in stuff that you generally need to build out in other environments (can you say security and replication?).
New features additions are incremental. I'd guess what you ask for is not a 'point release new feature' but would be something that might happen in R10 or later IF you can get anyone's attention and get it in queue. Your best bet might be to go to IBM Connect this winter and meet with the project managers; they're generally quite available and love to talk to folks. There are usually open sessions for Q&A, again, the folks are just awesome in these environments.
There may also be third party tools that could assist. I only use TeamStudio Configurator but there are a few high quality tool shops so poke around and see what pops up.
You could also see if there's anything at OpenNTF.org.
