iogames,
Yes, I plan to continue updating this plugin (testing a new version now). Even if I got hit by a bus, and had to stop for some reason, it's open source GPL and somebody else could take it up...
Now that Google has made this feature official (up to v1.6 of this plugin, it was undocumented), I don't see it going away. It may need to be updated as things develop in WP and at Google, of course. That's probably what most of the updates will be, though I do have some new features coming in 1.7 as well (probably next week).
If you have suggestions for further development, please share. But I do rely on this plugin for several of my own web sites, so I have incentive to keep it working. ;) As long as I'm doing that, I'm glad to share it with the community that has shared a lot of great stuff with me.
