I have been looking for an IDE for some time and I think I may have finally found something I really like. It is called Code::Blocks and can be found here. Most of the ones I have found just seemed to want to impose their will on you a bit to much. It is written in C++ and released with a GPL 2 or later stipulation which is just fine! It does use wxWidgets instead of FLTK but whattayagonnado.

I was able to point it at my GCC/Cygwin installation and compile a test FLTK application with little effort once I found all the places to get the settings to stick. It imports workspaces and seems to have quite a few nice features. It does seem to be lacking a block indent/unindent but it is still being actively developed.
