it seems I've hijacked this thread, but want to throw out another screen for feedback
ITEM MENU IS UP!
I ended up adding a few more windows, not liking the fact than when looking over items, you didn't have a quick refresher of who was hurt the most. So, I created a new window that takes the same space of Window_Target called Window_TargetAddon, which acts like a base placeholder of the party until you click on an item. This allows me to choose an item after assessing the party situation quicker and more conveniently.
Also, you'll note that the item menu itself is grid-like (icons are still base) but each icon still has the help window to the bottom of the screen giving the basic info of what each item does. I still have the single and all target cursors, all compatible with Mousie, and looking schweeeeet!
Also, Rather than dealing with hotkey windows popups that simply say the key is activated, I've created 1-touch control, so that by only hovering over an item, you can press the corresponding number, to add it to your hotkey.
FUTURE IMPLEMENTATION may allow you to see the items ON the hotkeybar, from the item screen.
