Here is a short list of things I would like to see implemented.
Shift-clicking: Please create a toggle option to "shift" click items into your bank, trade, inventory, etc. interface. This allows us to not right-click and becomes very convenient for pking, drop parties, banking items, etc.
Scroll Wheel Zoom in/out: I think this is a very much needed update. I find it annoying having to revert to the tool tab to zoom in/out of a fight, etc. Please add the option to either zoom with your scroll wheel or "ctrl+scroll wheel".
Custom Yell Tag Ticket: The ticket itself is untradable. Please allow it to become tradable and have infinite uses allowing you to edit your title at any time. Atm you need to contact @Gretar to have him add it manually to your account.. that's inconvenient for him and us, IMO.
Tentacle: Please add tentacle for either 3k or 4k inside the pkp shop, the tentacle should degrade after 10k hits like normal and be auto-keep.
Thanks for reading, hope at least 1 or 2 of these suggestions are added!
