This filter may apply elsewhere, but I find especially on the Feats List as your content options grow that there are a large number of Feats which are “Locked”.
While I love that they are there and I can just click “Unlock” to see which expansion they belong to, in situations where I am just trying to quickly create a few NPCs with the ones I do have, having the option to hide the Locked ones would be REALLY helpful.
Also, if there isn’t a specific reason you’re doing it, allowing people to at least read the locked Feat / stat might sway them as to whether or not they want to buy the content, so something to consider there as well.
