We love the log requests history option in the composer and over time we build up several hundred items. It would be great if there was a simple text search of urls and content to find logged requests we want to tweak or rerun.
Less important we would love the ability to drag a request from the capture listing to the log request history to use later
It would be better to save the request rather than needing to execute it first, just in case you don't want the side-effect of the request being made at that time.
By "Less important we would love the ability to drag a request from the capture listing to the log request history to use later" do you mean that you'd want to drag/drop a Session from the Web Sessions list to the History List directly, without just dropping it on the Composer and executing it first? That should be a trivial change for Telerik to make.
