Check Boxes on time blocks are cosmetic

[intervolver]

Several features that would be nice:

• Allow checking off a task in the planner itself
• a setting so that newly created blocks do not default to checkboxes
• the ability to enter text directly into the newly created time block, similar to the way kanban boards allow direct entry into new cards

Yeah I was very confused as on hovering the checkboxes an interaction cursor pops up but they are not clickable.

The issue in the title is a duplicate of #304. Please create separate tickets for separate feature requests so as not to confuse them.
