Though some of these may be seen more as feature requests, it's small and technical enough that I think it justifies being here. In addition, some of these should be grouped together just following Vanilla's example

-Dyed Quark items aren't grouped unlike most dyed Vanilla items (planks, shingles, candles, slimes, quilted wool, etc.)
-Leaf carpets, bookshelves, ladders, and possibly chests(?) should be grouped like most other wood variations
-The sheer amount of slabs/vertical slabs makes the recipe book messy. Grouping the initial recipes for slabs (i.e., 3 blocks), with the vertical slab to normal slab recipes, would reduce a lot of that
-Generally, a lot of recipes that give the same items in return should be grouped

This issue is still in 1.15
