Change Stuff Without Restarting

In MCreator, whenever you need to change 1 number in a setting or add a single block of code in a procedure, you have to quit the client, change the stuff, start it up again, wait for the game and world to load, all just to see you did it wrong, rinse and repeat 10 times. It's really annoying.

When making data packs, (not in MCreator), you can change one little thing and do /reload to reload the data pack and test the change.

It would be nice if this was possible when making mods in MCreator, or if something like this was added.
