First minor revision of my mod version of Headspace2 plugin under new name gdHeadSpace4 is released fixing several more issues caused by tags integration code I missed first time around. Right now plugin looks very stable, but more changes are coming soon.
I remove some additional code that was causing problems on the post edit pages and some code on the category edit that was also giving several warnings in some cases.
Please, test new features and report problems in the forum or in comments.
