[Idea] Toogle todo button could also turn not a todo tiddler into a todo

[es-kha]

Hello Nicolas,

For non todo tiddler the "Toogle todo" button could turn them into a todo (add a todo tag).

The new tiddler "states" triggered by the button would then be:

Not a todo --> todo <--> done
    (new part)   (existing)

I see this as an "irreversible" action (except by manually removing the todo tag).

Best regards,

Eskha
