Some tweaks and fixes.
- Sometimes a player will keep an effect from the drink on respawn. They have to rejoin to fix it. Less of a problem for things like motion blur and head movement, but a friend of mine got permanent god mode from a drink even after dying.
- Add some sort of category system for the drink effects to sort them better and make it easier to find certain effects.
- Add a advanced mode to the editor that will allow you to choose sounds/materials from a file path instead of a preset one.

Some extra options for the drinks cosmetically.
- Changing the material of the drink.
- Changing the text to be local, open, or server chat.
- Ability to make the drink emit light.
- Drink does not appear until the dispensing sound stops playing.
+ Maybe have an empty cup spawn first.

Some more drink functions.
- Make the player emit a sound.
- Make the player emit a sound client-side.
- Make the player emit a sound server-wide.
- Make the player glow.
- Put an outline around the player.
+ With a custom color.
- Launch the player.
- Freeze the player. (Player can still take damage while frozen)
- Lock the player. (Player basically becomes a prop.)
- Show a material on the screen.
- Show an overlay on the screen.
- Kick the player from the game.
+ With a custom reason.
- Make the drink instantly explode upon being dispensed.

Some advanced functions that would require more work.
- (Function) Make the player see a image from a webpage on their screen.
- (Function) Temporarily teleport a player. (Teleport to this pos for X seconds and then send them back.)
- (Function) Ragdoll the player.
+Possibly custom radius of ragdoll effect on nearby people.
- (QoL) A example of Post Processing effects on the side of the screen so you can see what the drink will do the the screen without drinking it.
- (Cosmetic) Ability to make the drink switch between multiple colors
+ Intervals for each switch
+ Fade time (0 for instant change)

These are all possible in one way or another, and they would be a cool addition. I would be willing to help with some of the more advanced things if you want me to. A lot of the functions I added would only be anywhere from 1-15ish lines of code so not too bad.
