Redmine

We would like to create customer views (create , edit and follow ) on our issues managed in redmine. The redmine own gui is not usable in this case, furthermore we wanna embedd this cutsomer views into our portal or company website deeply.

To be able in our onw gui to trigger issue watching we need a rest api to add or remove watchers on issues.
At the moment the Rest_Issues does not support watchers at all
