The "history" view feature can be separated into two different "views":

1. Plans overview list
   This should list all of the plans and an overview (date created, total basal consumption per-day),
   with the following capabilities:
   • View (read-only) each plan (using BasalPlanListView).
   • Delete a plan from history (should require confirmation).
   • Set the plan as current (?).
2. Plan View
   This view should be opened when a specific plan was selected to view in the previous view.

Add a developer mode that enables using a different firestore collection while developing.

Overview

This utility enables keeping track of changes to my basal plan.

This is important for two reasons:

1. If my pump conks out, the plan remains accessible even if the screen stops working.
2. I can view that were made to the plan (could be interesting and enables going back).

Data

The plan(s) will be saved using Cloud Firestore

Capabilities

The utility will have the following capabilities:

1. View the current basal plan.
2. Edit the basal plan.
   a. Add / remove segments.
   b. Set segment rate (U/hr).
3. View plan history.

To switch from ListView to AnimatedList, we need the following changes:

• BasalPlan's methods to return the indexes of the changed segments.
  • added
  • removed
• Implement animations for the adding / removing.
  • note: animating an edit operation doesn't seem to feel correct

Create a guitar tuner utility, which can be used to tune the guitar in different tunings:

• Standard
• Drop-d
• Custom
