Today I finally took a look at the extension store from Creator (by using the Packages -> Extension Store menu item)
All of the items listed in the store have names and descriptions in Chinese only. More importantly, the interface is in Chinese only.
I tried to switch the interface to English by hitting the (EN) link, but Creator gave an error message: "Not allowed to jump to external page."
Please consider revising the Extension Store interface to include an English interface. I would be interested in both using and creating extensions, but I am unable to read Chinese.
