From Almar's idea, we could make some really nice reprs for notebooks kinda like what xarray does 😄

For graphics we can have an expandable table with the following:

• name
• features
  • data, can be expanded to show the head and tail of the actuall array, or whatever the array repr returns
  • colors, get all the unique colors and show the actual color with a box using the RGB values if there are <10 unique values?
• position
• List other features, draggable, etc.

For graphic features:

• name and value of the feature
• if it is for a Buffer, be able to expand and see the buffer head/tail (like data in graphics above).

For plots and gridplots:

• expanable list of graphics in the main plot area with the names
• graphics in the docks
• name of subplots, if a gridplot
• adapter info
