on stash option, anyway to make it support multitabs on same categories? like [currency -> 1,2] means if 1's full or un-available then goes to 2? I also need rares on many tabs since bot just stopped running after my 2 designated tabs are full, even tho I still have 6 more tabs empty.
Yes, stashing options support multiple tabs. You can use comma 1,2,3,4 or hyphen 1-4. Please read Cross-bot Settings description for more information.
