Describe the feature

Currently, whenever bags are closed and reopened, the bag is redrawn. This causes items to move around, sometimes jumping from one row to the previous or next. For instance, selling a few items and then reopening bags might mean fewer items exist on a row, such that items from the following row now get placed up on the former row.

It would be nice to prevent BB from redrawing bags until asked. That means that row and column of each item is fixed, even after bags are reopened.

This would be super helpful when doing a lot of back and forth between selling, auctioning, and banking. For instance, I might be at the auction house. I put up several items, so they are no longer in my bags. I note several other items that wouldn't make a profit selling on the AH, so I decide to sell them instead. When I go to a vendor after leaving the AH, this option would guarantee those items for sale would be where I left them, positioned in my bags, and I wouldn't have to hunt them down again, or run back to the AH to verify I have the correct items to sell.

Describe the implementation

A lock toggle would be great, just an icon up next to the bag icon. When selected to lock, bags would not be redrawn ever. When selected to unlock, bags would be redrawn as normal.
