Stash slot memory / smart stash

How about leaving a "shadow print memory" behind in slots where you've placed items?
Normal left click + drop a item marks a slot automatically with a memory of the similar type.
You can set the transparency level in options.
If you wish to remove a memory mark use Ctrl+ right click (it's a unused shortcut, faik).

The memory applies to general base types of items; orbs, gems, jewels, cards, maps.
This feature is basically a auto-arranger once you've set it up.

You can for example have only 1 of each of these orbs; chaos, alch, alt, chromatic.
You then mark a 3x4 area in the top left of the stash tab,
"painting" it by picking the chaos up and dropping it on all those slots you want to mark.
A 4x5 area on the bottom left for the chromatics, and the remaining center area for alts.

Now this tab is set up with a preset memory.
You go out, farm a ton, and once you unload at your stash you just ctrl+ left click all your fresh loot, and the orbs will (priority based) automatically fill the slots which you've marked in advance!
Everything goes where you want it to go, instantly! No more fucking manual tuning or splitting stacks in advance again and again, no more bullshit, just instant gratification.

Smart stash 2.0, Yes please dear Santa.

It should look something like this, the marked slots (reserved) have a faded out currency icon
(without the number "1" on it, blame my lazy photoshop skills).
