A quid is a slang term for the British pound. So currently, 1000 quid (or 1000 pounds) is about $1500 US dollars.
Sidebar is a theme feature introduced with Version 2.2. It's basically a vertical column provided by a theme for displaying information other than the main content of the web page. Themes usually provide at least one sidebar at the left or right of the content.
But when I click to view one of the posts, I go to a full-width format, and the content from the Main Sidebar is laid directly on top of the content from the post. Itâs not in a column to the left of the blog content, itâs sitting right on top of it. At the end of the post, thereâs the Extra Sidebar content shoved way down to the bottom.
