One very useful feature that could also improve the "perceived" performance of the system would be to provide the capability to save "filter by" settings for the view.  

This way the number of records shown when you account can be set by the user, and by setting it a shorter period the time taken to process and render the records can be reduced.

The option to this can be triggered by include say a option "customize view" by the user clicking on the tab for the account, and would enable the user to setup the filters and save.  however not all will pick the tab menu, and hence adding a context based menu option to the "view" for account view customization would also ensure its used and understood by all.

Would be great to see this feature get include into this feature rich application.
