Re: End or stop when...
It's very complex. You may view the filter files in the .config/filters directory of @Voice app home folder, but to understand them is another issue. I don't have any good documentation for them, only some text files with notes for myself, and when I don't understand any more the notes, I have to look at the old filters I made in the past. You must also look at the website DOM tree (in a web browser right - click any element and select "Inspect". And then, if I find out that I cannot filter correctly some site, I enhance the app code to make a new feature, and release an app update.
