1. For targetting a special file, see Spybot Christmas Presents, Part 2: Separate File Scanner
2. For Firefox, there are already great generic protection plugins: NoScript and AdBlock, for example. It's somewhere on our todo list though to write a specific Firefox plugin as well I've added this issue to the bug tracking/feature request system though to allow votes and comments on the topic.
4. The browser page overview already allows you to change entries (see Change button in the toolbar). Do you want that button to be available in the context menu (right click) as well, or have I misunderstood your point?
6. For utilities, I would recommend RunAlyzer as a stand-alone tool. It's going to replace the integrated tools section in Spybot-S&D 2.0 RunAlyzer takes a lot of time to start up as well, that's true, because of it's integration check. Requests for specific combinations to be added to the startup selection are welcome.
7. The option to temporarily disable already exists, and the 2.0 TeaTimer is already concepted as a system service and with some other plans to make it more persistent
X. In RunAlyzer, you can already copy entries to the clipboard. I've added this feature request for direct browser links though.
Sorry that I skipped some entries, just used a short break in working on the new TeaTimer which I need to get back to now
