I have two accounts and on one recent stays till I hit the button. On my other it sorts before I get a chance to look. i cant find a setting for this is it just a bug?

At some point I right clicked the S on the top right of the bags. And it sorts new into categories on open close. But right clicking S again does not disable this?

Also could we get an option to split soulbound and non soulbound items? I keep selling stuff I want to send to my enchanter.
