Welcome to the Breww Community, and thanks for sharing a great idea.
Firstly for planned packagings - if you add these to your batches, Breww will show them on the batch schedule. When adding a planned packaging, you enter the date so if you know for example that you can only package 500 cans per day, you could enter 500 cans, three times on consecutive days rather than entering a total of 1500 cans. This would then be represented on the batch schedule for you.
For other steps/tasks, we’ve been toying with how best to do this for a while. We’ve been thinking that you could add “batch schedule events” to a recipe. These could allow you to pick an icon, enter some text and a number of days after the batch was first transferred to a vessel (typically the day it moves from the brewing system to the fermenter). We would then copy these from the recipe to the batch on start of the batch and allow you to add/modify them as needed on a batch-sepcific level.
These events could then be shown on the batch schedule and would allow it to be really customisable to the information that you’d like to show. You could add notes like “Drop hop”, “Filter” or “Start carbonation”, for example.
How does this sound to you? If you’ve any other ideas of how this could be done better, please do say.
