So what's keeping us busy these days?
1. Revising Modeling Techniques – Its time to catch up Eclipse's standards. We have decides that our previous modeling technique is getting oldish. So naturally we are targeting JDT's concepts with adaptation to the php dynamic binding nature (given by the DLTK project).
2. Code Manipulation – sometimes the editor should generate new code or even rewrite an existing code. This is an excellent mechanism for such kind of tasks. Also a great advantage is that we catching up JDT's standards on these capabilities as well so many of JDT's features are quickly portable to php.
3. UI enhancements – this is the part that our community should be most happy to hear about. Since infra was enhanced , more and more UI features are available. Taking for example mark occurrences, override indicators, better code completion, fast searching, quick fixes and more.

5. Unit testing – Well... maybe it won't be an interest of any of our users but still it is worth mentioning. We have tripled our unit testing to provide stability and regression testing to PDT. It seems that it also makes the whole development cycle more fun to us!
