Adding a tablesorter to client list etc.
It would help a lot if the tables in the background could be sorted with a javascript plugin like e.g. http://tablesorter.com/docs/
Another benefit would be that it is visible after which column the data is currently sorted (which I can't see at the moment.)
In one of my projects I use the tablesorter plugin along with the tableFilter plugin: http://www.picnet.com.au/picnet_table_filter.html
This allows to have full full filtering and sorting on the client side only.
