Make it easier to edit a linked fieldset

[aerni]

It would be a really great UX improvement if a click on a linked fieldset would take you to the fieldset's edit page. I find myself clicking on it every single time, only to find that this doesn't work.

Clicking on the linked fieldset opens this pane right now. So there has to be a solution that accommodates for these settings as well. Maybe the fieldset could be edited in this pane. Similar to how you can edit fields in a Grid fieldtype for instance.
