This is one feature I’m really behind, been waiting for it since release. I’ve tried to organize my bank multiple times but out of a lack of space/time it always ends up getting jumbled again. Besides needing to constantly move items around and dig through the bank tabs, we (at least this is how I do it) need to haphazardly search for items and combine rogue stacks in hope of clearing up more space. Needing to constantly bother with my bank to make it usable is pretty crazy.
Please Anet, this feature would save so much time! I love the search feature, but that alone barely makes up for items not stacking into each other and some kind of sorting function.
