IntelliJ’s Idea 6.0 Beta is out and available free for evaluation. The most expected features were GWT support, TeamCity integration, UI designer enhancements, and productivity/editing features. I have not tried (yet) UI and team integration but here are some things that caught my eye.

Built-in Code coverage support – Programmers love improving their code and what better way to do this than seeing coverage percentages of your tests right within the IDE. If you are using unit testing a lot, this gives you good insights about where to focus your tests.

Project-wide error-highlighting – This is something that Eclipse had for a long time, giving you a good understanding of where you should go for errors without having to recompile.

There is one missing feature that Eclipse has: selecting a variable should highlight all usages in the current block.
