Whenever I join dungeons or raids as a healer, I always find myself frustrated by how the UI is layed out and the inability to customize the actual visual aspects of it. To combat this, I used to use a bot program called Lasta which had a plugin that allowed you to pull up an overlay which gave you the same functionality that Grid+Clique would in WoW for those that are familiar with it. Unfortunately, it hasn't been updated in quite some time. Is something like this possible with RB at all? Here's a video showing it in action. https://www.youtube.com/watch?v=p02ZyE9OMCI
Not sure. Easy temp fix for click casting: make a autohotkey script that sends an extra key for mouse buttons.
It's not totally optimal, but UltimateCR more or less does it for you, I agree that the UI is utter shit in FFXIV though.. barely customizable and generally made for consoles.. Like gathering is pretty damn atrocious on PC.
