Aside from the obvious stuff, the best thing about this extension is total customizability. Otherwise it would've been bloated with too much functionality, but nope, I can disable everything I don't want and only keep stuff useful to me. Keep it up, guys.

Its almost perfect. But on Linux OS, if extension detects linux operating system, PROTON DB links should be enabled BY DEFAULT (just to make things easier) cause it's important information source for linux users

This extension is great, it turns the store into something useful, collecting all the needed information in one place.
The only minor problem was with the pricing of one bundle, which was I think converted in euro from the price in usd, without considering the taxes (so it was reporting a slightly lower price than it should), but it's understandable.

text in store page review got really big and you can not read more when the text overlaps the review box.

Great features added to steam. Only thing I miss is a login/account/save function so all my notes also is visible in Firefox and other devices.
A list of all notes would also be nice that can be exported.
