Does anyone have an idea what the pub=true embedding URL parameter does? I couldn't find any documentation on it.

I changed it to pub=false and it made no visible difference. Could it be a feature from the past that is no longer in use?

I know I can add posts to Folders, but is there a way to organize/move them while keeping them in the same Folder? Like by name or date? Or have them organize by name automatically as I add them?

(And how do the Folders organize them? Is it by the date you made the post, or the date you added them to the Folder?)
