Are you a player who is fond of multiple play styles? Perhaps you are tasked with switching the items on your hotbar frequently, and you wish you could save a copy of how your items are arranged? This suggestion will help you.
My suggestion is essentially to add "snapshots" of how items are saved. Essentially, there are three empty "frames" which can be used to save inventory layouts. There are located on the top-right of the inventory near the crafting grid, as shown in the image below. By default, all three diamonds appear as red, meaning they do not have an inventory saved to them. When the player clicks one of these red diamonds, their current inventory is saved to that slot, so that if they were to click it again, items are rearranged in their inventory as they were when they were saved. The diamond turns green. Deleting a class is as simple as right-clicking the green diamond of the class you wish to delete.
In Creative, items are spawned in when classes are changed, regardless of whether the items are present in the inventory.
In Survival, only the items of the class that are in the inventory will be organized.
NOTE: This thread is largely a work-in-progress. I will be adding more explanations, pictures, charts, and even animations.

You know who can tell me something I already know? Me. All the time. I'm really good at telling me stuff I already know. I don't need help in that department. I don't know about others, but I can't imagine I'm alone here.
I'm sorry, but do people really change their inventories around between presets they come up with that much that we need this? My hotbar has exactly one standard arrangement, and if things need to move, then I move them. Despite the fact that I wear many hats (ranging from explorer to engineer), arranging my inventory has never been so difficult that I would wish to click a button and have it already done.
Could you explain the situations you get into that make you want this? I think that would help me understand more why it's needed.
I follow a fairly standard layout for items on my hotbar for pretty much everything I do. The exception comes when I'm building things, but then I usually don't mind going to my inventory to swap things around more often so long as I always keep a sword in slot .
