I want to propose something that will improve QOL a bit maybe 1%. Here we go 

1. Make villa invitation accessable trough whole family instead rather than item that have to remains on the char who hold the invitation something like this UI concept below.

*Hell yeah put all the things related to buff there nice and tidy.

2. When you click the new UI button then will show you a list of villa buff you already bought like this pic below

*Jae Kim's Villa who give buff +53 enchancement?when?

That's all. All these ideas is under MIT Licence. LOL
