+1 for the "edit assigned issues", as the "edit own issue" permission only lets you edit those which you directly create and not the ones which you are assigned to, could be also solved by adding a setting in the "fields permission" workflow setting if there was a "Additional fields permissions when the user is the assignee" like the ones for the status transitions in the same workflow setting.

Hello! Sorry for disturbing. Maybe there is a method to edit only assigned issues? Maybe i can change some configuration file to change "own issues" to "assigned issues" becouse "own issues" button is not so helpful for my purposes? It wold be very helpful if somebody know how to do this.

I managed to provide myself with an "Edit assigned issues" permission by applying the :edit_assigned_issues aspect found in the "issue-permissions-1.1.0.patch - bugfix2" patch that can be found here: https://www.redmine.org/issues/7444

(Redmine v4.2.1 in my case)
