I don’t mind dated, but I do wish the UI has a few more modern windows touches like being able to ctrl select multiple conditions/actions in the ELE, proper page up/down scrolling and sorting items in folders (without the item getting kicked out of the folder). It would also be nice to be able to expand all sub groups of a specific group, rather than expanding absolutely every group in the frame.
These are more quality of life upgrades, but I don’t know if they are possible in 2.5 anymore. As for outdated, I thought the only old tech involved unloading some cpu tasks to the gpu. But maybe I am incorrect?
