To find that, you have to go to the home page, click on "community", then "get involved", and then find the little "donate" tab. I went looking the other day and gave up.

Put a friggin' button in the dock on every machine that shows whether you've donated recently. If they can put Amazon affiliate links in the main interface, they can just ask me directly for money.

I initially thought that the idea to integrate Amazon was a very bad thing - but I think it could be useful. I use Amazon for many purchases, with the shopping lens search results from Amazon will be available via the launcher.

However, I think the lens should be easy to disable - especially since user data will be sent to a third party by default. At present the package can be removed, but this might not be intuitive enough for some users [1]

I also think the store / aggregator associated with shopping lens should be configurable to avoid providing Amazon with a monopoly over other sellers.
