Redmine

Hi, I am new to redmine and to redmine plug-ins...

I want a feature... something like a "Assign me" contextual menu link...

The idea is to be able to set the "Assigned to" field and the "Status" fields at the same time, so when the mouse is over the "Asign me" button the menu shows me the possible statuses I can set to that issue(s)

Do that feature exists in another plug-in?

If it does not, how can I develop it? Is there a "contextual menu" hook? Where can I see an example?

Thanks in advance...
