Days with unfinished tasks happen, deal with it. Better still let US deal with it for you!
Edo Agenda provides a way to automatically move all the today's unfinished tasks to the next day.
The tasks are moved when the day changes and this automation affects only the current day's unfinished/not-done/unchecked tasks (to move unfinished tasks to a different day you can use the Move unfinished * buttons).
Web App
To activate this feature on the web app you can click on the three dots in every day page in Journal and toggle the button Automatically move unfinished today's task to next day (we hate obscure labels, you know...).
From the day you activate the feature, each day the unfinished tasks will be moved to the next day.
If you prefer you may activate the feature from the Settings (the gear icon a the bottom left of the page) > Profile and again toggle the Automatically move ... (I did it, so useful...)
iOS and Android Apps
On the mobile apps this setting is in the same places: Tap on the three dots menu in a day page or open the Settings menu in the left side menu and then check the Auto move unfinished tasks setting.
Please note that this is a Premium feature feel free to try it during your trial period.
Fun doesn't end here, todo-list and notes references can be auto-moved if you want. Please check this how-to to learn how to create them and set the auto-move on each reference.
