+| Aliases       |             |           |  X  |         |        | Aliases allow for shortening large commands, while passing flags     |
 | Notebook      |             |     X     |     |         |        | Initial jupyter support, but it loses state and lacks features       |

 | Plugins       |             |     X     |     |         |        | Plugins work on one row at a time, lack batching and expression eval |
 | Errors        |             |           |  X  |         |        | Error reporting works, but could use usability polish                |

 | Paging        |             |     X     |     |         |        | Textview has paging, but we'd like paging for tables                 |
-| Functions     |             |     X     |     |         |        | No functions, yet, only aliases                                      |
-| Variables     |             |     X     |     |         |        | Nu doesn't yet support variables                                     |
-| Completions   |             |     X     |     |         |        | Completions are currently barebones, at best                         |
-| Type-checking |             |     X     |     |         |        | Commands check basic types, but input/output isn't checked           |
