This is useful for modded villager professions and Minecraft newbies alike.

I didn't knew it was JER that showed Vanilla Profession, so I asked for this on JEI's tracker.

If possible, could it be for 1.16.5 too, since most important mods are still there?

It would be awesome if it acted like a recipe block as well so if you get the usage of the profession block it includes the villager trades. As it is now, it can be a little annoying to get to the desired trades page
