For those who use my SMN Lua, I've published a major revision so I wanted to make a post about it.
Here's a link to the Lua: https://pastebin.com/Fa5PtueC
I've totally revamped the aftercast set usage. It was built in a restrictive way because it was just designed for how I use it personally.
I decided to make it smarter because of how many people started using it. You now have full control over making aftercast sets for whatever situation you want. For example if you want a different DT set with Carbuncle than with other avatars, you can add that and it'll get used.
Also, you can add your own idle modes now and as long as you add a set with matching name, it'll be used like you'd expect. I think a lot of modern Luas are like this so I apologize for taking so long to make mine this way!
Please let me know if you have any problems with the Lua. I don't get to play SMN as often as I'd like these days so it hasn't been thoroughly tested yet.
Happy summoning!
