Glow ink uses

The Glow sack is an under used, but very cool part of the game.  I have three places it could be implemented I think could make lots of players happy.

1. The same way you can change the color of glass and glass panes with other dye, it could make the glass have a glow turning the glass into a light source.

2. If you could use it with Trim patterns on armor, it could make glowing armor. How cool would that be!

3. What if, hear me out, you could put it in a potion to give you......"water vision"......like night vision but making the surfaces under water while you are underwater illuminated and crystal clear.
