Indented / collapsible sub-issues in Roadmap
On the roadmap page, it would be great if there was some kind of visual indication of sub-issues, i.e. if Feature 101 has sub-issues 102, 103 and 104, then the roadmap would show:
-feature 101 |-feature 102 |-feature 103 |-feature 104
If this could also be collapsible (with a remembered "collapse all" tickbox somewhere), that would rock.
