Hi Jelle,
Unity has got better, but it isn't perfect. I pretty much stopped using Ubuntu and went back to Debian when it first came out. I installed Ubuntu 12.10 mainly to check on progress. Generally it has got better but still not quite right. I agree on the Amazon shopping lens. It should have been opt-in, not opt-out. Quite easy to fix if you know what you are doing, but perhaps that is not the point.
Here is a screenshot of the current trophy viewer (sort of like a trophy cabinet). All the trophy icons are kind-of "samey". We'd like to add variety. In terms of number of designs, I am really not sure. Speaking with people on IRC it looks like we would like something like a template file, where we could make some simple edits ourselves (colours and maybe icon in middle of trophy). The group would love to discuss more with you, do you use IRC? If so we can be found in
#ubuntu-accomplishments we also have a mailing list via
launchpadThank you
