[Feature Idea] - Send task back from Today to Backlog

[mausvargas]

I believe this would be a good feature to have, in case you put as "today" a task that wasn't supposed to be for today, but you don't want to delete/recreate it.

I guess a "Backlog ↪" button or something under it whenever is on the "Today" Tab.

Will try to implement if I have the time soon, but whoever want to go ahead and do it also would be awesome. 😃
