So I'm just going to put things into perspective for people in regards to what it takes to do the UI.
It took 4 hours to add a tab ("Miscellaneous Options") and "Allow Discord to display your location" and the UI filter options to the source client. Those are literally a tab, and several checkboxes that then set an option in the configuration.
Adding a sort function prompt to the interface has a few key factors that can make it difficult, and or impossible to do. The first of which is if it is at all possible to add a prompt in the first place, and that is somewhat dependent on how they've coded the sort function and if we can call a prompt first. That is also dependent on whether or not there is a prompt in the inventory UI element, or if we can call a prompt from outside of the UI element. It is then a matter of whether or not it is possible to do the change in the source files, because the tools that have to be used do not always allow you full access when you are reverse engineering the UI files.
DP was made in such a way that rather than it being re-usable elements or assets, it is entirely hardcoded to be for specific use. We will look into it, but given how time consuming it is likely to be, it is not going to be a priority because it is not as simple as just adding a line or two to the code.
