Free and Open Source Software

(First post, let me know of any cultural "faux pas")

As many others I struggle with managing my day to day/week/month/year/decade, so naturally I'm looking for some kind of TODO-software.

I'm trying to find an open[1] format for todo-items and -lists that has the capability to give recurring todo:s the attribute of "droppable" so that an individual occurrence can be "dropped".

It would also be fantastic if the format has an inbuilt way to keep track of what individual occurrences have been "done" or "dropped"

This would allow me to keep track of things like:

• Medicines: recurring (sometimes many times a day) with a fairly small window if opportunity, if I don't take them it should be noted but there is no way to do it later so it should be "dropped" from the main-list.
• Bills: recurring with a few days of being actionable (depending on when I get paid and the bills due date), if I don't pay them it should be made higher priority until I pay them, this should also be kept track of.
• Cleaning windows: recurring, with a big window of opportunity, but if this particular spring is a bad one it doesn't matter, this should be dropped and there is no need to keep track of it.
• Things that are considered "habits" (like personal hygiene, exercise, cleaning, practicing musical instruments, etc). These should be dropped and tracked.

The goal is to be able to produce a fairly short list of things that I can[2] do right now and absolutely bury things I can't or shouldn't do.

If there isn't any decent format I will most likely just force one of the two mentioned with some kind of appropriate extension.

[1] open in this context would be some kind of standard like VTODO or just openly available like todo.txt

[2] can as in MUST / SHOULD / MAY
