Nice hack

I'd like to ask something...
I don't like the cells to be one under the other like this :
-
-
-
-
-
-
I would like them to be like 2 or 3 of them in each line... like this:
- - -
- - -
- - -
this way we have 9 latest threads which take more space horizontally and less verticaly.
I would also like this to be cetralised and not aligned at the left side of the board/page.
I guess I would have to put the $threadbits in a table and then centralise the table? (align=center)? Right?
could anyone help me with these modifications??
thanx in advance
