Add Creation and completion dates

[FranciscoTrigo]

This looks very cool! I currently use todo.txt and im thinking to change to this.
Maybe the format can have optional creation and completion dates for items?

A way that I think this can be done is in the first line of a long description (or the second line of the item) like this:

[ ] Paint the room
Created: 2023-02-01 Completed: 2023-03-04
More description if needed

It would probably be neater to choose some kind of symbol or abbreviation to denote Created and Completed instead of using the words.

One way to kind of make that happen right now would be by using tags, and establishing your own convention, such as:

[ ] Paint the room #created=2023-02-01 #completed=2023-03-04
[ ] Do something
    #created=2023-02-01 #done=2023-03-04

That would also allow for tooling support, along the lines of “give me all items with tag #created where the tag value is smaller than 2023-02-15”.

Oh that actually sounds pretty neat, I honestly did not understand the use case for tags with values before this, very nice.

Yeah, good point about the use-cases! I’ve added some demo usages to the project homepage, I hope that helps others to get a better idea.
