We **may** want to support setting a few basic meta-data fields for milestone 1 in the side-bar already.
Most importantly, a custom preview image.
Others we may want to expose already:
[ ] Description
[ ] Author
[x] (rBc4aba77211e8) Tag (if filtering by tags is supported) -- Simple UI-List until we have a proper tag-list widget.
[ ] Name? (Currently the asset name is always the name of its ID. Should this be optional? Should we show a text button that would edit the ID name?)
