Screenshot with narow index pahe that truncates section titles

In the Index pane of the evince window, the contents of the document is shown
as a tree. This is good. The bad is, this pane can be narrow and evince only
shows truncates the document's sections titles, to fit the width of the pane.
If the sections of the document are nested, their titles in the index pane are
offset to the right according to the nesting, and often you can only see
three-four letters from the section title.

There is no way to scroll the index pane horizontally, and the evince does not
show a full section title text as a tooltip when mouse pointer is hovering over
it. And it is not very convenient to resize the index pane every time you want
to see the contents and then resize it back when you want to read the chosen
page of the document. 

The index pane would be much more useful if it had a horizontal scrolling and a
tooltips with complete section title. 

And I would suggest removing ellipses (...) that indicate that the section
title was truncated. This just adds to the offense of not being able to see the
full section title: in place of those ellipses, couple more letters of the
section title could be made visible. Similarly, the page numbers could be
removed - they also truncate section title. At least, displaying page numbers
could be a user preference option. 

I'm attaching the screenshot image that illustrates the problem.
