It would be really helpful if we could add and customize components in PlusSpec Component Tool. There really aren't any items common in the US. I want to be able to add categories of information to items too.
It would also be helpful if we could create our own "types" of walls, windows, doors, ect., instead of only the types shown. I really like a lot of the tools so far, I just need more customization in order to successfully use it here in the US.
