Sometimes it is very hard to know,
who is doing what currently in the team.
The "in progress" status could be helpful for such cases.
Thanks for the suggestion. It's unlikely that we will make any major changes to the issue tracker in the near future, but we will keep your suggestion in mind if anything changes.
That said, we use "New" for issues not begun, "Open" for issues under development, and "On Hold" for issues that are in development but paused.
