Undo check-in deletion

[0AgentSmith]

If a check-in/status is deleted, the user is redirected to the dashboard.

As a lot of information can be attached to a check-in (description, tags, etc.), I propose adding a (short-lived) recovery option.
A temporary notification shown on the top right hand corner of the dashboard (where error messages usually appear) could do the job.
It disappears as soon as the user performs another major action.
