Button placement mode

Use the mouse wheel to iterate through the visible frames to choose a parent for the button. When holding down ctrl the mouse wheel will resize the button instead. Finally click to place the button.

Sort order

The highest priority is to fill special bags (e.g., herb bag) with fitting items.

Besides that, the primary sort order is:

hearthstone mounts special items (items of arbitrary categories that tend to be kept for a long time for some reason. e.g., cosmetic items like dartol's rod, items that give you some ability like cenarion beacon) key items (keys that aren't actual keys. e.g., mara scepter, zf hammer, ubrs key) tools other soulbound items reagents consumables quest items high quality items (which aren't in any other category) enchanting materials herbs common quality items (which aren't in any other category) junk soul shards conjured items

The basic intuition for the primary sort order is how long items are expected to be kept around. The more "permanent" an item is the lower it is placed in your bags.

Within the primary groups items are further sorted by itemclass, itemequiploc, itemsubclass, itemname and stacksize/charges in this order of priority.
