If one wants to open the text of a function from within a document (by right-clicking on the function name), the function opens not in the "next"/side-by-side tab to the current document, but as the last in the list, which - if more than 5-6 documents are open - is a pain.
It is also impossible to just drag the opened function (or any other opened document) side by side as needed ( fast switching).
