-implement the new enchanter, without replacing the old one, with a recipe from what it looks like (like a holystone sideways-H, with ambrosium in some parts)
-new Gravitite armor (specially because the new texture

-dexterity cape for the voteshop or dungeons (silver/gold), this cape gives you extra speed (speed I i belive)
-valkyrie full armor functions (wings that let you fly for 3-4 secconds), and the cape (works like the golden feather)
-golden clouds functions; pushes you downwards (usefull to keep mobs on a certain place)
-well, the new clouds with functions (green/purple), hopefully they get implemented on the voteshop :/
-implement new building blocks (walls and stairs of carved/angelic/hellfire/skyroot log/holystone), to avoid too much IDs usage, then use damage value
-new trees (saplings available on the gui shop or voteshop or dying a skyroot sapling)
-show health of mounts
-(you may disagree) show capes from Aether II donators
-skyroot crafting bench, doors and chest
-swetty pendant (lets you climb walls), to make this one less op, it lets you climb 5 secconds (and maybe add more time when more acrobatics level)
-Deadmau5 ears

Bonus: ideas that are not from the original Aether I/II, to add some unique stuff, and some other suggestions too
-Aercloud shield (shield slot), makes the player inmune to the aerclouds effect (still prevents fall damage, its like stepping on a normal cloud)
-RGB capes!! (like leather armor)
-RGB leather gloves (it should be like that)
-Skyroot armchairs
-Tables?
-Armor stand (add this goddamit XD)
-New pet system; gui button that lets you know your pets, where thery are, and their health
-Blue aercloud poof? made of blue aerclouds like a parachute, when you right click you jump (even if you are falling/already jumped) like you step on a blue aercloud, of course 1 of durability
And in a "far away" future; new dimension, Aether II
-hope you agree with them ^.^
