Sorry, yes, Record Macro is in UO:Assist + Classic Client and will allow you to access just about any item, skill, or gump in the game. It is identical in function to a mouse recording macro program, which would otherwise be illegal for use with UO.
Personally, I would like to see us able to tear off crafting tiles similar to how we use skill and spell icons. Same for spell selection gumps such as polymorph and animal form. I think this would go a long way toward balancing the issue of Macro Record without robbing the UO:A people and without compromising the EC. UO:A isn't Mythic's responsibility to support, but it would be foolhardy to screw over that mass of users.
I really see no issue with being able to craft two dozen potion kegs in one macro when I can spam a spell 1000 times over in a single training macro.
