Optional ability to only tick / untick on the current active day

[redfox05]

Add the ability to essentially disable future and past days from being edited. On small screens it is sometimes easy to press the wrong day.

Alternatively, add a filter option to only show the current day.

The latter option however, in order to look nice might mean a significant change to the UI when that filter is active, as it would mean only one column is shown, so instead the items could be shown as cards in vertical stacked order.

A workaround that solves this problem is adding a few "Checkmark" widgets on your home screen (or on a separate home screen if you have many). They are easier to access and to tap, and they only apply to the current day.
