The new Forums aren't working very well this morning...
The idea that highlighting a keyword in VS and pressing F1 might actually become a realistic way of accessing the help is easily the most exciting thing about this. It's been years since I even considered that way of working, certainly not since the first VS.NET release.
Other than that, I'd like to have something like team annotations or MSDNwiki hosted on a local server, so my team could add comments and notes specific to our processes and projects.
Also, if you're not aware of it, the inimitable Verity Stob discoursed at length on the shortcomings of MSDN help in an article here: http://www.regdeveloper.co.uk/2007/03/08/msdn_gloom/
It's humorous in tone, but the points are all valid. Especially "yes, thank you, I know the function signature, but what's it for?"
Second the call for smaller download formats. I watch C9 videos on a PDA on my commute, and I'm sure many others do the same. Currently I download massive files and then re-encode them for Pocket PC using WM Encoder, which is a bit galling, really. Also, the big downloads push my internet usage to a level where the IS guys ask what the hell I'm doing all day.
Of course, if you didn't keep putting such interesting content up, I wouldn't be downloading anything at all!
