More Creative Inventory Ideas!

The new changes to the creative tab so far look amazing, but I think it can be further improved for an even more enjoyable experience.

1. Sort by Color tab

This tab would sort all blocks by color. It may be a little harder to implement, but I think it would inspire people to use more gradients when they build, and play around with color more instead of feeling overwhelmed trying to find a block that's, like, 1 shade darker than red wool, or 3 shades lighter than blue wool, or trying to figure out what blocks of one color look "softer" compared to other blocks of a slightly different color.

2. Make every block available through the creative inventory

Plain and simple. Personally, it doesn't make sense to have blocks that you can only get with commands. Especially since 1.12 added the Creative Toolbar that you can add these command-only blocks to, but I'd like to be able to reserve that Toolbar for specific layouts that I need instead of using it to store blocks that should be readily available to all players. Barrier blocks, Light blocks, and even Command Blocks can be very useful to builders. Also, with this idea, please add the Petrified Oak Slab back into the Creative Menu!
