Currently when starting to insert a new page link with `[` + the first few characters of a page name, the autocompletion appears and shows matching pages. Unfortunately the autocompletion dialog does not show which spaces the results are from (or it shows it as a mouse hover hint which nobody finds), so it often happens that a page from another (wrong) space is selected. This is especially a problem for huge Confluence instances with hundreds of spaces and thousands of pages.

Suggestion: show the Space next to each autocompletion result
