Have a way of logging time spent on a bug

Ability to fill a time-to-solve estimate, and abillity to see this in the bugs overview

A timetracker should be implemented into the bugreport function, a teammember can add how long they've been working on a bug. Or if the bug is "In progress" and the status gets changed to "Resolved" the time you've been working on the bug will be filled in automatically

To be more complete, we can consider that generally a ticket receive an initial estimation to be solved and then an effective time worked on.
Should be possible for a developer analyze a ticket, put in an estimation (visible only to developer team members), and then put in worked time highlighting if worked time save or exceed initial estimation. This could be very useful for Project managers in order to estimate revenue of current work.

that will be a useful feature. I can use this for planning more comfortable.
