Ideas for post-CLI version

[benkeen]

Stuff I really want to add for the next big version after the CLI code is finally released:

• revise the UI for selecting a Data Type. It's gotten way too big.
• Add a "% empty" option
• Add a "omit from output" & have those rows visually show up differently in the UI. These rows could be used to generate stuff which is then used for other rows only.
