What's the "selling point" of this mod?
This mod is not easier or harder, it makes "more sense". I will describe you one function that I liked (besides "feudalize tribes button"), it's the faction system. In addition to usual annoying factions, there are 4 more - one of them cares for gold and only gold - give them low taxes, and suddenly they are not only neutral to you, they are kinda your friends. Another faction may care about tradition - if you educate your heir with the wrong culture or religion, or attack too much of your fellow believers, expect an ultimatum. Other faction cares about glory - just conquer and make our country great, and they're happy. So this is perfect example of something that is not harder or easier, but makes more sense
Also, if you are not prepared for much more provinces, or are still in love with the 769 bookmark, don't install the module called SWMH
