Double click to open existing project
It's a commonly implemented UI pattern that when a dialog has a list that you can select elements from and a button to commit to that selection, double clicking an element on the list performs both actions (selecting the item and clicking the button).
It'd make opening existing projects (a fairly regular use-case for Burp) a bit easier since the first dialog that appears when opening Burp requires selecting a project to open and then clicking on a button in a distant corner of the window (Enter/Return doesn't activate that, it rather moves the selection in the list box -- WTF).
Thanks for the suggestion, this sounds like a good idea. We’ll look at implementing in a future version.
