Hi again,

FIltering is possible by clicking the arrows that appear in the headers:

The buffered view is great for scrolling through stacks of data:

The main decision is whether to do the filtering, sorting and grouping
on the server or in the client. Ext.js is good for doing both methods,
and javascript is pretty fast these days!

Is the workhorse of the server-client communication.

A disadvantage of ext.js is that it tends to look a bit blue and
business-like. There are some themes available, but if they don't fit
the design it can be a bit of challenge to style the css.

Hope that helps,

Donny.
