Highlight current revision in revision graph

Hi all,

After trying the shiny new TSVN 1.5 and playing around with the Revision
Graph I still haven't found a n option to highlight the current revision
(sort of "Where am I on that big graph") depending n the current
branch/tag/trunk. (This has proved very useful in a clearcase environment,
so why not have to usefull parts in Tortoise too)

Expected behaviour:
After selecting a checkbox "Show current position" the current latest
revision of the current branch/tag/trunk (or subdir of it, if there exists a
branch for it => best match) should be highlighted (e.g. show an eye icon,
write a big fat "current" there)

Current behaviour:
No option to activate this view (I hope a haven't overlooked something very
basic.

If that sound interessting it might be worth opening a ticket or it. Comment
welcome.

BR
