With these changes the small 'edit' icon at the top right of each widget will work.
It will show a panel where the configuration item of each widget is presented.

The review of this PR can be started but I've one thing I want to fix on how we save the configuration, mostly a polishing so if people want to test, this should already work.

Maybe, only show the edit button if there are widget_arguments available?

Looks good! :)

Yup that's one thing I wanted to do, unless we include the 'Remove this widget' button in this panel.

I may forward the entire widget object to the template instead of just the id to be able to do such logic.

Did you mean cur_config here instead of config?

Good catch, thanks
