While formally Qt Creator supports the Debugger Log window, it's not very friendly for debugger interaction: it prints a lot of unrelated internal logs, the actual GDB output is mangled with escaping, and it's split into three parts with no clear purpose.

Please add a dedicated debugger console which would behave exactly as an interactive debugger session: in a single text window, with editline-like command entry, and debugger output exactly as the debugger provides it without quoting nor escaping.
