I just had a look at 0.5.5 in order to migrate our
0.4.2 installation
and would like to suggest an improvement of the classic
schema:

The navigation at the end of the issue index table does not
tell how many issues there are altogether and which of
these I am currently looking at. It also looks bad if
the table only has one column.

Attached is a patch which puts the navigation into its own
table inside the last line of the outer table and thus
ensures that on the left side there's the (optional)
"<< prev", centered in the middle there's a "xx..yy out
of zzz" 
text and at the right there's the (again optional)
"next >>".
