I disagree. I use sort constantly throughout the day and I have 4 retainers and do a lot of gathering and what not. This game already has confirmations up the wazzoo in fact it's awful at times. Like you gotta click a check box just to click the confirmation to delete certain items from your inventory lol.

I mean I've had those moments where I was sorting all my gathering materials I plan to sell to the bottom right of my inventory so they are away from everything else for me to easily look at and see how many I have then I accidentally sort it. Minor inconvenience that does NOT equal the inconvenience that would be created from having a confirmation box. You will waste significantly more time on a SORT confirmation window than correcting your mistakes from clicking sort accidentally.
