from where I can download the extension ?? can I used with app inventor?
You can get it here
I asked you on another post about some capabilities of this extension.
I think there are a good idea if the show of previous (or average, etc.) califications could be scalable (or streetchable), and could representate fractions of stars.
I’m using Material Icons .ttf font, that has 3 kind of stars: full, medium and empty stars.
This is prety hard to buid all combinations, but works fine.
