While i dont think these will actually be all that valuable as indicators, it felt appropriate to add them alongside the block colors. I quite like how they look.
Showing tabs for (in order): All Blocks + Items (All non-redstone + non-light indicators have both block AND item versions), Alphabetic blocks + items, Main blocks (blanks and templates), Block Color blocks + items, Decorative blocks, Light Level blocks
Showing tabs for (in order): Misc Items (including palettes and erasers), Numeric Blocks + Items, Paints, Redstone Level Blocks, and Text Color Blocks + Items
The blocks on the ends are the template blocks. The blocks are shown in left-right order of how they are listed on the Wiki. The Palette item cycles through the colors in this order.
The alpha block off to the side is the template block, used for crafting all the letters
Numbers. Values. Math. Pretty self explanatory.
