WebUI's Dom Explorer lets you "spy" on the AUT.
From the Recorder windows just click on the DOM Explorer icon to begin exploring your application (screenshot 1). Alternatively you can highlight an element with the highlight element and then use Locate In Dom Explorer from the pop-up menu.
In the DOM Explorer you bring up additional info on an element by right-clicking on it and choosing "Properties" (screenshot 2).
On your second question - you can edit elements from the Elements Explorer in your project now. Would you please describe your use case. Let me know exactly what you want to do and what features would make your work easier!
Hope to hear from you soon!
