Sometimes urgent stuff (e.g. production issues) come up during a sprint.

It would save time we can add these directly to the sprint. As now I need to add them to the backlog & drag them into the sprint.

This is not logical since there is a difference between a backlog & a sprint.
And adding sprint-work to the backlog first is counter-intuitive.

This could be implemented by a simple "Create" button at the bottom of the sprint which adds it to the current sprint just as if I add it to the backlog + drag it into the sprint thereafter.
