Comment

This is what I presently use for writing D programs. The only drawbacks are the project management isn't very sophisticated and you'll have to spend some time configuring the Tools section so you can compile and run without having to use a command prompt. The upshot is that it has some of the most solid keyboard and mouse handling I've ever seen. - Eric
