Default values

[stevenbird]

Snap blocks generally come with supplied values for arguments, e.g.:

This means they can be tried out with a single click, and it helps users know the expected type of the argument.

I think we should have arguments specified for many Edgy blocks that expect an atomic value, such as an integer (but not ones expecting a list, say)

• some blocks on the network tab, e.g.:
  • generate... blocks
  • adj blocks
• some blocks on the nodes tab, e.g.
  • add node (1)
  • remove node (1)
  • node (1) exists
  • set (shape) of node (1) to (circle)
  • (shape) of node (1)
• no blocks on the edges tab
• all blocks on the external tab
• some blocks on the collections tab, e.g.
  • counter(item, 3)
  • dict(key, value)
  • stack(item1)
