Something I noticed in 1.5 and 1.6 and this happens even if I completely wipe my UI and fresh-install and use your settings.ini file (1280x1024). The order of the hotbars are (top to bottom) 5, 2, 4, 3, 1 instead of 5, 4, 3, 2, 1. Easy enough to fix, but I wasn't sure if it's saved in the .ini or if that's a Sony bug?
edit: Oh, and just noticed you switched to the OCD style Inventory. How in the world do you get it to remember the mode you prefer? I keep setting it to Paperdoll, but everytime I camp and come back, it's always back in Slimline
But at least the Drop to Inventory is fixed now.
