Nice little tool.

Couple of observations (not really affecting the functionality):

1. (as said above already) - it's sufficient to use /wait 2 for non-touch and non-synth commands
2. There is no need to specify .0 in the wait commands - just use /wait 2 or /wait 3 - so you can default to 3 + 2 in the setup frame instead, also no point in alowing to enter decimals there
3. There is no need to put the /wait after the last command
4. There is no need the wrap the single word commands in the quotation marks - so Rumination can be used instead of "Rumination" for example.

Feature suggestion:

Filter to select which skill user have, preferably based on the class and it's level - let's say 8 drop down menus where you can select your current lvl for each class to list your currently available skills.
