I think no one wants to go through the work of creating a full featured client. What most people want is just adhoc customizability. For this reason, the web is great if you know how to code.

For example I do a lot of simple stuff with greasemonkey scripts like making stuff sortable or filterable, creating a bulk download and rename button, or just customizing appearances/css.
