I’m having a hard time believing this feature/plugin doesn’t already exists and i just didn’t find it during my search. On my phone i often struggle folding a task after i’ve checked it without dechecking it by accident.
Could also be neat if the parent task could automatically check itself out when all its children task are checked, but that might be better as a separate feature. Or Maybe this should be a “Task checking comportment plugin”. Again, i doubt there isn’t already an automation plugin that i’m not aware of which could do the trick. Maybe not for the folding though. Maybe with Creases.
