I’ve just released Version 8 of WebViewTools Extensions which includes a number of requested features, including getting the source HTM of a website, triggering an event if there’s an error loading the page, and switching between mobile and desktop modes, check it out!
Good question, I have managed to block popup and redirect ads in the past using the SetOverrideURLChange method, however this would only work for one domain at a time, if you want your users to go between different websites this may not be a solution for you.
It’s funny you say that because I just had someone else message me with that issue, there were actually some bugs with the RemoveWebView function. I have now released a version 9 which fixes these issues and adds a new feature, OnProgressChanged event.
