well not much code was added this week. However I have tried to install my PMA fork to as many machines with as many configurations as possible. By doing so, I have found few bugs and made some fixes which will help with the compatibility.
Who would have ever thought that I would find a machine with no JSON capability. After this not usual encounter I added check for JSON functions and if there are not any, then tooltips are disabled.
Next week is the last week of GSoC and I will work on documentation, more testing and fixing bugs if any.
