Right, some quick announcements before I go to bed.
1. Mad_Clog, I Have added your patch, seems to be working fine.
2. I have added a jquery based popup for the edit file link. Seems to work ok, and kind of matches the default SS popup (more work on this to come :) ). This is based on Greybox Redux (found at http://jquery.com/demo/grey/) and is a pretty impressive, uber lightweight popup engine.
Both these changes should now be in the trunk.
Uncle Cheese: I can see what you are doing, and it is a good idea. But I am concerned that if you try to make this too modular, then you run the risk of breaking the layout.
It would also be wise, I feel, to maybe limit the number of plugins that can be active at one time. Otherwise you can end up with a massive list of modules that just becomes chaotic and inevitably defeats the idea of quick simple summary of your site.
I will try and have a look properly when I get some time. I want to try and close some existing bugs before doing such a drastic re-write.
Cheers to everyone so far for their input :)
