Custom dashboards

Hello everybody.

First of all I hope I am posting in the correct forum, since I know there are two different versions of Pentaho: the one which is driven by the community (Pentaho CE) and the "standard" one. In my case, I am not using the Community Edition but I am instead experimenting some basic reporting with the Business Analytics trial version that can be found here: http://www.pentaho.com/download.

I have a question about the dashboards of Pentaho. I would like to change some graphical aspects of the presentation of the dashboards. In particular, i would like to hide the vertical and horizontal scrollbars when they are not needed (currently they are disabled and it doesn't look so good).

Other things I would like to achieve are:
- modify the background color of the first row of the tables (dimensions and measures names)
- set tables to be shown in the center of their widget
- set colours of the table's rows after the first one in order to make it more readable (for example white-grey-white-grey and so on)
- hide the filter pane

I hope there is a solution...
I am also ready to modify some code if needed in order to achieve my objective.

Thank you very much in advance!
