While refining the internal developer dashboard, Lena needed a way to quickly strip out specific status codes that were cluttering the team's view. Mark reviewed her plan and suggested a helper that shifts all the useful entries to the beginning of the list, allowing the interface to ignore everything else. For example, if a list contains items like [ready, busy, busy, ready] and the team wants to hide the 'busy' items, the function would rearrange it so 'ready, ready' are the first two entries and tell the system to only look at those two. This keeps the platform’s data clean and efficient without the overhead of generating entirely new lists.
