RE: Window matching – I did see the long list of apps with unique IDs etc, but surely sloppy window matching is better than none? I’ve seen a lot of people with dedicated desktops for certain ‘roles’ such as messaging/email – web – development – music and these all require a unique set of applications. Using KWin it’s trivial to just ’sticky’ to a certain desktop and when closer/reopened will open where requested. I think that’s the only thing that metacity misses out on at the moment for usability – stickiness/state.

If you put it in and people use it, great. If not, hey you’ve done your part. People can patch any offending apps or you can sloppily match for those cases.
