Speaking of the user problem set:
When you're writing down user documentation, you'll probably become aware of things that are completely impossible to explain to any normal person
(for example "to make someone a site-wide admin, visit /permissions, then select "Object 0", and grant "admin" on that object to the person you wish to make site-wide admin").
File these as SDM bugs, please, so we can start cleaning up the user interface. It needs attention, and there's *tons* of low-hanging fruit, things where we could just add a page or two, or do really small things that'd help much.
