Consider the sorting methods available in Baganator (e.g., "Blizzard", "Sort by Item Type", etc.). Note that via the native Blizzard UI for bags/backpack, it is possible to flag a specific bag for "ignore during sort".

Consider 10 items dispersed in the following way: Items 1-5 placed randomly throughout personal bag 1 (16-slot "default" bag everyone gets), items 6-10 placed randomly throughout bag 2.

1. Via the native Blizzard UI (must disable Baganator temporarily to see this), right click on bag 1 (16-slot) and enable "ignore sorting".
2. Re-enable Baganator
3. Set Baganator sorting method to "Blizzard"
4. Open bags and select "sort"
5. Note that items 1-5 in bag 1 remain randomly dispersed. Note that items 6-10 in bag 2 are sorted in some fashion relevant to "Blizzard" sorting method
6. Set Baganator sorting method to "Item type"
7. Open bags and select "sort"
8. [BUG] Note that items 1-5 in bag 1 are sorted by item type alongside items 6-10 - i.e. non-Blizzard sorting method overrode preference to ignore bag

This leads to a particular type of chaos / unexpected behavior when considering the following: #171

This is normal, and there's no plans to change this.
