I would like to welcome Stefan from Google as platform.ui committer
Stefan used to be an Eclipse platform developer working for OTI and has indicated that he would be interested to work again on Eclipse platform.ui.
Stefan indicated that he is interested in working together with the Mylyn team to bring the notification system to platform.ui and also that he wants to port the e4 databinding generics implementation to platform. He is also working on performance and stability enhancements in various areas.
Stefan fixed lots of bugs in the Eclipse project in the past. If you check the Git commit log for Platform UI alone he contributed more than 500 fixes. His recent fixes included a tricky fix for the re-appearing toolbar in the IDE, whichis every useful to users.
Welcome Stefan!
