Vanilla refabricated features a huge amount of visual changes to the game (with a few mechanics)
TRMT (A terrain erosion mod that makes grass, sand and leaves erode when walked on too often, also adding a lightness effect which prevents the erosion)
Easy Magic (Items stay inside of enchanting tables and the ability to reroll enchants)
Trade Cycling (Allows you to cycle villager trades with the click of a button)
Ipla (Allows you to place items on blocks, simular to item frames)
And more...
The modpack will get updated to newer versions occasionally
