I think both changes are good ideas. I rarely find the default HTML view 
useful, and usually switch to PmWiki view. I also enable InlineDiff on 
all my wikis, as this is considerably more useful than the old PmWiki way.

I guess the real question is why would we *not* do this? I'm not really 
seeing any downside.
