As a user I can't "feel" this bad code at all. Sure, it's has It's own philosphy of things and ocaasional bug like every software, but it's still one of the most stable and productive apps I know. there are regular updates, no big deal breakers and faults coming from the project itself. It simply works and grows, despite being so complex and powerful.

So what is this "bad codebase" you seem to feel?
