Ace

These are very common component Addons required by many other Addons. They provide handy libraries particularly for things like the Options UI Windows. I did my best to Include Ace with any Addons that require it but if you have an Addon that is Dependency Disabled because you do not have Ace then these are the droids you are looking for. This pack contains all 3 and it is safe to install all of them even if some are not used.
