Something I've been meaning to ask, probably going on years now that somehow escapes memory every time. How do you guys manage inventory on 5-20 characters?

What addons do you use?
What strategy on bank / guild bank depositing?
What kind of macros do you use to one-click sort / deposit / withdraw from bank tabs?

Lots of questions for sure. Going into BFA I need to sort this out. I've personally struggled with it for years.
