I'd like to see dialogs such as the recorder window and test execution window docked in the browser like a toolbar. Sort of like how QAWizard from Seapine does. Likely would have to be an option and maybe only for certain browsers, but it's convenient.
Ability to save (.t) script as (.exe) executables. This would make SilkTest a powerful development environment. As for concerns about fewer license sales Segue could sell the "Enterprise addition (which contains the save as .exe feature)" for alot more than the standard version.
