I made these some time ago and having seen someone else submit a few scripts I thought I'd add these for good measure ;-)
sbols:
Lists SBo packages by date order.
'sbols 10' for example will list most recent 10 SBo packages installed. Use '-r' to list from beginning.
'sboup' will check for sbopkg update and optionally download, install and merge .new files.
ph (package history):
Lists packages by date order, most recent first.
'ph 10' for example will list most recent 10 installed.

The main site
http://www.unrealize.co.uk has further bash scripts, slackbuilds and some themes etc too.
