I originally started writing my own macro, but then thought surely someone else has this already... but I wanted to be able to use the same macro for different recipes between different chars, as well as simply allowing a bit of easy flexibility without editing the macro
I also sort of fixed the error where occasionally the combine button never gets pressed - something happens with the UI elements and the ContainerCombine_Items window just fails to be seen (i could get this to occur when i opened and closer a random bag (not 100% of the time) and if i had the experimental window open before the macro was started (again not 100% of the time) ) Really not sure on the underlying issue.
Now you can just use the macro if you know the items you have and have them in your bags, just stand near the kiln/pottery wheel/oven etc and spell it out for the macro.
Also, if you happen to move away from the kiln/forge etc while it's running, it seems to crash EQ (not sure why, as if you start it too far away it'll fail to work but it'll work that out itself in a few cycles
