More Efficient Inventory Functions (Specifically Stack Splitting/Sorting in Vendor/Personal Management)

More Efficient Inventory Functions (Specifically Stack Splitting/Sorting in Vendor/Personal Management)
This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Add Modifier keys (Shift/Alt/Ctrl) or radial option to split item stacks in predetermined or specified increments.
AND ,possibly, add an option to sell a stack of items as individual items when listing them.
Justification
Quality of Life for listing large stacks of items in smaller stacks and/or individually.
Motivation
HAVE YOU OR SOMEONE YOU LOVE BEEN INVOLVED IN AN ACCIDENT WHILE VENDORING LARGE AMOUNTS OF ITEMS?! Yes? That's weird... Don't do that.


Seriously though, I have spent an enormous amount of time taking stacks of valuable loot and crafted items and having to Go to Inventory > 'Right-Click' > -Split- > Type "1" > Return to Vendor window > List Single Item > Repeat when stocking my vendors. Clearly a time-sink, headache, and safety concern (Since I completely omit the "Rinse" step altogether...)

DISCLAIMER: I have only been playing for a bit less than a year and I'm continuously learning "new" things, so I am fully prepared to be told that something like this already exists. However I have been unable to find any info regarding this through web searches, personal inquiries, or extracting information via torture.

Thank you for wasting your time reading this!
