@Denzel what version of FFXIV are you using?
It's 8 steps for my version (FFXIV PC ENGLISH), however the original code was for 7 steps, I alway wonder why it's 7 per macro.
Also try clicking the "End Macro Echo" option, it'll change the macro to 7-steps and a "Completed #1..." echo at the end (which you can ignore).

@HEC

1. Adjust the Buffs option to 2 or 2.x whichever suit your liking then hit Generate, 3.0 is nice in laggy places.
2. The X.0 for show, you can do 2.5, 2.2, 2.9 etc... It'll just copy it to the wait time. Shouldn't be a bother since you will just need to copy the entire text.
3. Will look into removing that (inherited from original codes).
4. Wrapping everything in quotes since it doesn't affect functionality (lowest working denominator) same as line 2.

Feature suggestion added to future upgrades - Though it would default to everything @50... too much options is confusing to the users.
