I finally had a chance to look into it and it looks like the template was never designed to highlight that particular link.
If you want it highlighted you can try editing the default.html template file as follows.
Replace start of the second line after <% if ($_SHOW_VIEW) { %> which looks like this:
<TR><TD BGCOLOR="<%=$_COMMAND_OPTION_BGCOLOR%>">
with
code:
<TR><TD BGCOLOR="<%=(($TODAY_DATESTRING == $DATESTRING)?$_COMMAND_OPTION_SELECTED_BGCOLOR:$_COMMAND_OPTION_BGCOLOR)%>">
The rest of that initial line stays as it is.
This is untested but should work but as always, keep a backup of original fines just in case.
