• Quick chips for caffeine and nicotine can be turned off (web): Settings → App & Display → Home display lists the quick chips for each tracker, uncheck the ones you never use and the diary card shows only the ones you log
• Scroll wheels in the custom caffeine and nicotine dialogs (web): picking an amount is a scroll instead of a typed number, matching Android; the nicotine dialog takes the count and an optional mg value, and caffeine spans 0 to 500 mg

• More OpenAI models in the picker: choose GPT-5.6 Sol, Terra or Luna, or GPT-6 Sol or Luna from the built-in model list. Opening the picker also pulls the current GPT lineup from OpenAI with your saved key, so new models show up without an app update; offline or without a key it uses the built-in list
• Day-type colors across the week strip and Progress charts: each day-type profile can pin a color from an 8-swatch preset. The hero chip and the week strip show it, untracked days get a hollow ma

It gets its own chip on Home, stays out of averages, trends, the weight forecast and adaptive goals, and stops the streak reminder. You can still leave a rough calorie figure for your own record.
