Q:

What do you do if you ask a question that you regret asking?

I asked this question: How to make a "footer" stick to the bottom of a facebox (jQuery plugin) dialog
Some time after I asked it I realize that I should've focused on implementing some other functionality before asking this question (in this case, as mentioned in the question, make the facebox dialog a fixed size, and make a scrollbar appear in it if the content is bigger than the container).
I think it may still be a valid question when I'm done implementing the pre-functionality required to test it, but I know I'll be able to cut the question down and improve it by then.
I think it's also important to mention that the question has few views, no upvotes, a single answer, neither with any upvotes.
Should I:

Copy the question content (and save it as template for the yet-to-be-asked improved question) and delete the question?
Vote to close the question (since it requires 4 more votes, this seems unreliable), perhaps edit in an "Update" saying I want to close the question and rephrase it in a few days?
Leave it as it is, and perhaps just edit it to fit the answer(s) when I know enough about the issue to ask the question in a more useful way?
Do something else?

A:

Leave it as it is

The answer was given to the question as it stands - not to some version of it in the future tailored to the answer. 
Both the question and the answer may be of value to a future visitor to the site - seeing it is not being downvoted, you have no real reason to remove it.
When you have done the work to improve the question - ask a new one with your new found knowledge.
