ANOTHER TIP
One thing I noticed is: If you place the mouse over the tumbnail of the video and it doesn't start showing the animated highlights, it's a sign that you won't be able to download that video.
Does anyone know why when you are using mineiroloko to download from analvids it gives you a different video than the one you requested? Is there any other than mineiroloko that download?
These options had already been mentioned.
And I think the dev might put those engines after paywall if anything happened.
However, no alternative replacement with comprehensive function so far. (from my knowledge)
