I think there is already an extension that does this, even though I can't seem to find it right now. But anyway, why would I give myself the ability to accidentally click on some of these videos? For me, the faces act as a filter to ignore them.
Now that's a game I wouldn't mind a rewrite of. Imagine Heroes 3 with a modern engine and modding available out of the box instead of people having to reverse engineer it just to keep it alive today.
Hdmod (not the money grab hd edition) is a good nodernized version with lots of QoL, modding scene is active and there is also VCMI engine. All working fine
