WotLK ability queueing addon?

[memecuisin3]

hello, any addon setting or files that adds ability queuing like in retail/ classic wow? I'm so sick of pressing a key, the character starts the casting animation and then it doesnt do the spell/ability. In retail/classic, you press the ability a bit before gcd and it still casts it. If possible I'll give 6 coins or ingame gold on lordaeron for it lol. thank you!

Look up the addon "quartz". It's a cast bar addon that displays your lag in real time (on the cast bar) so you can adjust input/ability que accordingly.
