I am long time eclipse user and have been trying out the Idea 6 beta.
I like the integrated eclipse compiler and background compiling but i miss one feature which i really love in eclipse.
Eclipse allows you to run java files even if the project has errors. It converts these errors into runtime errors.
This is extremely useful in the sense that say I have 4 classes and 3 of them are complete. However I am still working on the 4th one and it has errors in it. Now if I want to run and test the rest of the 3 classes I can do so in Eclipse but I cant do the same in Intellij.
It would be great if you could add this feature to Intellj too.
