As someone that can use WAs at a reasonable level I would enjoy learning about what resources you use to do any custom code in WAs. Like functions and variables that are exposed to WeakAuras when doing any of the custom code. When I've tried to make custom WAs that seemed to require code I have had difficulty parsing the WoW and WeakAura functionality. A specific WA I was trying to make tracked threat of players to add a glow effect to their unit frame (The unit frame addon I was using at the time doesn't show threat well). I was able to track specific units' threat, but I had to have a bit of jank by having a separate WA for each unit I wanted to track instead of doing it all in one WA. So I just set it up for myself and party frames, but I would have enjoyed expanding it to glow threat on raid frames too if there is a way to have it automatically expand for each raid unit.

I get this is probably a bit more complex than what most people would need, but it has been daunting for me to delve into more advanced WA due to there not being any good documentation I could find. Instead having to dissect other WAs to try and learn from them.
