All 3 of these are quite annoying and just plain outright not needed or have a use.

The only one that seems to offer something slightly unique is the Realistic Item Drops mod where you can have items float to the surface if you must... But the Flat odd 3D ground stuff can be removed still via configs if you must have the floating stuff :)

Maybe suggest a Poll if you like to see if others use it but it just seems junky and messy I myself remove them all.

Well in lieu of an actual poll, here's my vote to keep them :)

I immediately removed all three, personally.
