### `deck.menu`
A library for easy menu systems for T-DeckARD programs. Allows displaying up to 10 menu items with the ability to select them with a single digit or a key on the `QWERTYUIOP` keyboard row.
Exports the only function, `menu(choices)`, which accepts a list of **tuples**, each in the format `(id, label)`. The `label` field is what's displayed on the screen, the `id` field is the string that gets returned upon selection. If the user selects `c`, the operation is canceled and an empty `id` string is returned.
### `deck.time`
A wrapper for standard Python `date`, `time` and `datetime` modules. Just run `from deck.time import *` to activate.
