If other people are going to start using this, let them input their own coffee and ideal ratio.

Now that you have the timings and amounts pretty much committed to memory, it would be more helpful if the 'main' page of your shiny app was actually a Dashboard-like page with the coffees you are currently dialing and allows exploration of your collected data.

It should focus on coffees that were brewed in the past week, and coffees where 'currently_brewing' == TRUE.

Regardless of whether the current stash is dialed or not, it should give a table of the last few brew-parameters, e.g. show line graph of this batch over time.

It could also be expanded to show historical data and benchmarks, e.g., for all similar brew volumes and method, show graph or table of mean draw down times. to see if this is within an expected range or not.

Right now, the logic for what temp and grind size lives in coffee_functions.R. That's silly. It makes it difficult to add new coffees if/when they deviate from your defaults.

The task at hand is to remove all of the logic from coffee_functions.R and just read these columns instead.

On UI, can add a tickbox that says "override timing defaults". Then, take in as inputs bloom phase, first phase, second phase, third phase? timing as well as amounts, e.g. "target total grams" for each phase.

Basically, give users the option to populate their own table.

Make sure to add differing methods for smaller vs. larger volumes.

This will be a bit tricky because the brewing time intervals are pasted/glued into the gt table. I'll need to save them off elsewhere and refer to them. I might need to generate a reactive statement/observer event that adds on row-highlighting when the stopwatch time is within each interval.

• Need to churn through existing Google Sheets data to figure out what best ratios are
• Port over changes to coffee_data.csv and push to shiny server

Not that the shiny comes up in search results anyway, but would be fun to do: https://shiny.rstudio.com/articles/google-analytics.html

It would be helpful to have an on-screen timer to use along with the gt table.
