I wanted to thank everyone and appreciate your wonderful ideas. This is the first version and i will try my best to do better works of mine and fix any bugs that exist in this mambot. I am going to develop this work by making a better control panel for this mambot in admin section and you will have a better control over its functionalities in the new version. By the way i had not that much donation for this work (maybe its not that useful) but in the next version i will probably remove the link back part in footer and also i will offer a full documentation for free in the case that you want to develop it your own way. This is my first Extension that i created so far so do not expect this to be that good, since i had so many emails about ajaxifying joomla i came to this idea for making this mambot so that no one would have this problem for ajaxifying joomla. Thanks again and please check my website for new updates and new versions of Joomlajax

Its exactly what i have been looking for, i waned to make one myself. The only problem that this plugin has is that it would only work when you set the "show in front page" to yes, and then it would place the diff button in frontpage and all the contents, however if you want to show it only inside contents, it wouldn't work. its better than you fix this problem.
