This more or less mirrors my sentiments. I use (g)vim pretty much exclusively,
so I don't really care about IDEs aside from how they help the community at
large (your typical IDE's editing capabilites are so much of a joke compared
to those of vim, that using an IDE really makes no sense for editing - for me
at least).
However, I would definitely like improved debugger support. I almost always end
up using writeln debugging except when I need to track down a segfault. Of
course, gdb support for _C++_ sucks in my experience. It can't understand
basic stuff like operator overloading. So, I wouldn't expect much from D
support either - though it would be really nice if gdb could at least
understand D strings. I certainly wouldn't be opposed to someone writing a
solid debugger which was D-centric, as it would really improve debugging, but
I'm not holding my hopes up at this point. That's a major undertaking.
