It would be nice to be able to drop items of the same type onto each other in the guild stash. When I have items in my personal bags that I want to put in the guild stash it doesn’t let me drop it on a stack already there. Take black lion chests for example. I have a small stack of them in the guild stash. Every so often I get a few questing. I go to the guild stash and I have to pull the stack out, combine it with the ones I just found and put the stack back into the guild stash.
This goes for anything else that stacks. It would be so much easier to just drag and drop into the guild stash without having to go through the unnecessary steps. Even combining multiple stacks from within the guild stash doesn’t work.
Example: I have 2 stacks of 100 candy corn in the guild stash. It won’t let me take one stack and drop it on the other to make one stack of 200. I have to take both out, put them in my personal bags to combine them, then put it back into the guild stash. It’s a pain in the butt.
