Heh, I asked for this once (even further, if Enyo, which is open-source now, could be adapted to Harmattan) and it was unceremoniously dumped in the "competitors" forum.

Preenv is unmaintained and is getting more brittle every day. I find it funny, however, that nobody is porting the WebOs Game Manager to the N9.

It must be so easy that any developer can do it with their eyes closed, so they see no point in building a user-friendly front-end to it...
