Documentation (like the text you are reading now) can always use improvement!
There's a list of issues that should not need deep knowledge of the system.
To dig deeper, read a design doc, e.g. architecture.
There's always code that can be clarified and variables or functions that can be renamed or commented.
There's always a need for more test coverage.
