Some Edit niceties such as being able to add tasks or encryptions to an existing todo or note

[figjeti]

It would be nice if some of the available flags for add were also available for edit. Often times one may not know whether or not they want something encrypted until after they have already created a note. Likewise as a project extends, it may be nice to add more todos or subtasks to an existing todo. There is an argument to be made that the latter can be resolved by just adding the markdown manually, however the former is a bit more tricky to deal with.
