Highlighing column against or in right hand scroll bar

In eclipse and delphi and winmerge when there are a lot items in a file selected or highlight (e.g. compiler error or differences of found symbol) there are markets in the scroll bar so it's very easy to find them all.

in sublime text 2 there are markers in the overview though not very visible and if the file is bigger than the overview the found item isn't seen

It would be good to have a highlight in the scroll bar for each match in the find all or current selections so one doesn't miss something.
