Headspace2 is great plugin for SEO. I prefer it much over other solutions like All-In-One SEO. But, problem with it is slow development and problems with WP3, unneeded features while missing features I need for my websites. So, I decided to work on my own version.
To avoid confusion with original plugin, my version is renamed to gdHeadSpace4. You can find it on the Free Downloads page, in the modded plugins section. New home page for this plugin is at the bottom of this post.
Plugin has a lot of differences from original. I removed some of the features because they were conflicted with some of my plugins (tags on the post edit panels and few other things). Plugin panels are a bit reorganized, icons changed, annoying support pages removed. Also, I removed annoying comments with license on top of each file, changed code layout to better fit to my editor (NetBeans). Several other obsolete modules, code that was causing problem on dashboard is also removed.
There are some new tags to be used for SEO elements, custom post types and custom taxonomies supported properly, I added filters allowing expanding of tags with custom tags. More changes will come as I need the make changes or find more problems. This is plugin version I am developing for myself, and I will not take ‘features requests’, but I will improve plugin from time to time and make it compatible with both WordPress and my plugins. If you find this version useful, please use it, if not try original version or some other SEO plugin.
Please, test new features and report problems in the forum or in comments.
