Suggestion: Dashboard-level formatting and description

[eshel]

1. Would be useful to have a general description for an entire dashboard (not for each individual chart). That way you can explain the purpose of this dashboard.
2. Ability to add sections in a dashboard. Each section will be defined by a Heading, A short description for THAT section (see above), and the graphs. This could be edited either as another "graph" in the drag & drop layout editor that currently exists, or via a textual formatter (see Dashboard filters #3 markdown).
3. Even better, allow power-users to manually edit a dashboard's layout using a markdown or similar editor. This will allow creating rich dashboards which are self-explanatory and possibly include images, "static" tables etc - all in one place.
