List any visual interfaces for debuggers that you know of!

[Hasan Aljudy]

It seems that there are some programs that can provide a visual user 
interface for debuggers, like Code::Blocks and Zeus Editor.

Can we make a list of these programs available so that more people know 
what their options are?

If you know any such programs, please post them here.
If you could also add simple directions/instructions for usage, that 
would be great.
