TLDR: For the love of god let our profession bags be made our default bags for those items!
This is driving me crazy. I have a large leather working bag and a large tackle box (for fish). Yet everything defaults to my new reagent bag. I even tried putting some things in the other bags hoping that new items would stack on top of them as I collected them. No dice. Everything continues to go into the reagent bag.
I am actually thinking about just getting rid of the reagent bag completely! But I just thought it would be nice to have other various crafting items go there instead of my main bag.
