Pro Easy to use
Con Lots of functionality is encountered only in plugins
You can't change keyboard shortcuts, neither share themes with vanilla codeblocks, for example.
Con Slow navigation using mouse
In most IDE's, you can "goto declaration"/"implementation" by holding CTRL and left-clicking on an identifier or include directory. This does not work in Code::Blocks no matter what settings you have. Right-clicking will bring-up a menu that includes these "goto" options, but it's not instant and you'll be slowed down immensely depending on how often you have to do it.
Con Not very feature rich
By default it's not much more than "What if Gedit had a compiler and a terminal built in?" (or: "What if Notepad had colour coding, auto indents, file structure, a compiler and a terminal built in?")
There are far more professional IDEs out there. This one is much too basic for any efficient use.
