For Dummies is a project of at least 2 modules :

"Builder" which helps you save and activate unlimited amount of action set builds
"Rotation" to generate a priority based ability cycle.

General features:

Use /fd or /fordummies command to open the option window
Activate/deactivate Modules (I used GeminiAddon to create addon-like modules)

Builder features are:

Use /fdbuild <strBuildId> or /fordummiesbuild <strBuildId> to activate a build
Save the currently used action set build (only the 8 abilities from the LAS are saved, I didn't want to save the gadget, path ability nor potion) in association with the action-set
Rename the build
Select one of the 8 ability icons directly from the build as representative icon for this one
Activate the saved build
Create a macro that will activate the saved build (do not edit the macro in any way if you want it to stay linked to the build)
Renaming or changing the icon of your build will update the related macro information instantly
Delete the saved build
Before activation, the addon switch to the correct action-set if needed
Before activation, the addon check if all the abilities are usable (in case you changed your amps and had an amp ability when the build was saved)
Before activation, the addon check if you are in combat or dead
If the build activation failed, the addon will reverse to your previous action-set if switch was made earlier
The addon prevent any kind of double click/activation

Builder planned features:

~~Add Tier number over the abilities icons~~
Add of an UI build swapper somewhere

I have not yet started to work on the "Rotation" module, I don't know what will be required and if it is even possible, so it might take a while

Personal note: This is the first time i make an addon and also the first time i work with lua language, so the work itself will probably not be perfect..
