A while back, there was discussion and general acknowledgment that it would be more efficient to show the available sub-panels as a row (or rows) of tabs under the current detail view, rather than having to scroll way down the page and expand each sub-panel, accordion-style.
This would look and behave somewhat similar to the row/rows of dashboard tabs at the top of the screen.
Has any further thought been given to this feature, as a general release? (not as a paid add-on).
