Process restock mailing operations first
Usecase: I want to setup my mailing operations in a way that I always restock X amount of an item on char A, Y on char B and send everything else my bank char.
Example: I want 40 food on my main, 20 on my alt and everything else on my bank char. Some food I cook on my main, some on my alt and some I buy from the AH on my bank char (because of recipe luck, curse you Nomi!).
Problem: Depending on the order the mailing operations are processed in (which seems to be random) I can end up with everything on my bank char and nothing on my main/alt, or nothing on A, Y on B and everything else on my bank char. The only solution would be to setup a bazillion different mailing operations.
Solution: Setup one operation for each char with the desired restock amount (already possible) and process mailing operations in this order (new!):
1. Restock operations to the current char
2. Restock operations to other chars
3. All other operations
This way it would always reserve what I need on the current char, then restock other chars and send what's left to my bank.
