Description of problem:
On bug details page, right before the "Submit changes" button, there's another one called "Start working". It switches the bug into ASSIGNES status and changes assignee to whoever pushes it.
The button name is confusing - when QE wants to start working ona bug (i.e. verify its fix) they definitely don't want to be set as assignee or change the status the ASSIGNED.
How about "Take Bug"? Presumably QE wouldn't be taking bugs from developers.
There already are 'Take' links for the 3 major contacts (devel, QE and docs). So non-devels like QE _are_ used to 'take bugs'.
What I'm going to do for this button is to hide the button and only show it when the bug is in a Pool and then only to the members of the team the Pool belongs to.
Button is only shown when the bug is in a pool and the user is in the team the pool belongs to.
