Check/to-do list, routine feature and urgency/importance level + emojis (on desktop/web)
I think a checklist and sub-task feature to add the ability to mark off calendar items that are finished and repeat common tasks easier would be beneficial. The current set-up makes it difficult to keep records of what was done and can get overwhelming to look at. The user needs to laboriously go back and change titles or descriptions to know what was successfully completed.
The checklist could be similar to height.app where there are just boxes to check each thing or crossing off the task. Checking something off just needs to be easy and simple with as minimal steps as possible. A check box or double clicking to strike through. If you want to add complication, maybe there could be a cute animation once something is crossed off. Have fun with it!
The "routine" function could be like putting in a note for the task and have the option to cross off each to-do of that routine. Then could be more easily repeated without filling in specific time slots. It could just have the entire block be <routine name> then inside it is broken down into multiple steps that can be marked off. If combined with the first idea, it could have a toggle-able option to cross off the entire routine once every sub-task is completed. For example, maybe working out is the master-task name and the workout routine is the sub-tasks. Then the description of each sub-task could be instructions for good form. Once each exercise is marked done, the master-task is auto-checked. Another use might be each master-task could have each sub-task being the steps to achieve it.
Emojis can step in for urgency, but maybe there could be a way to have a dot of color to represent urgency, maybe tied with amount completed. Having a visual reminder of urgency/importance might look like a color block, or WiFi like waves. It would tie in with the routine idea well by helping organize what is the most important when trying to figure out what to do with a wide variety of tasks that need to be done when there is no specific time to do tasks during the day.
The goal is to be more accessible to ADHD/neurodivergent folks (myself included) while also making task keeping visible, clean, and less overwhelming. Currently it's difficult for the user to know what they have successfully completed compared to what time has just caught up with and the variety of tasks in the calendar can get incredibly messy. The description box, while able to write in the tasks needed, it has no way of checking something off besides deleting it or typing <complete> and then the user has no record unless its external or its otherwise very laborious to do. The lack of detail can make looking at the calendar very overwhelming because its full of smaller tasks without having an ability to easily group things. Having the organization structures, and the ability to write sub-tasks, would keep things clean, organized, and all in one place and makes it easier to know what part to start with. Checking something off also gives dopamine so it feels good to use Proton Calendar, improving customer retention and making the app easier to use. Emojis are just fun and a nice QOL change.
