It looks interesting, but I'm not sure if it'd better to wait for the next releases, for the server side.

Isn't it too focused to arts? I'd really like it if it had link to citeulike or to download my papers stored there.

They're initial focus is the humanities, but it's really done well. You go to citeulike and the folder icon appears in your toolbar. Clicking it will import all references on your current page. It also has automatic import for endnote format references, so if you click on download into endnote links (connotea, citeulike, etc generally have em), it automatically imports. I just tried this with my citeulike library using RIS export and they all imported including the citeulike tags - didn't import my pdf's on citeulike, but where I had access imported pdfs from original page. It also exports into all these formats. Give it a try. A few tips - in Preferences.. enable automatic pdf collection, and in Advanced tell it to store stuff elsewhere - by default it stores them within your firefox profile folder - I like to have my own folder. It also has a nice openurl resolver, so if you don't have the doi/url/sici/pickarandomuri you can probably still locate the paper using your institutions openurl resolver or crossref's friendly one. I personally use http://bioguid.info/openurl.php cos it's got a focus on taxonomic information.
