angular.js doesn't have custom support for edit-in-place, nor are there any plugins. Instead a solution can be built with the means already provided. Just place the text node and the input field next to each other and then use the ng-show and ng-hide directives to display one and hide the other. Both directives check a variable with can be set using a function called from ng-click or any other ways used to trigger the edit mode. It doesn't get simpler than that.
Didn't manage to confirm any users yet, but will continue to work on that. In the meantime i'll think about a landingpage for them to go to. And hopefully the jump issues when editing can be fixed too.
