Hi,

I had a short look at the current UI and the test-repo and found some usability and design flaws:

* when no text is available in the users language the statement section looks like this: http://lbenedix.monoceres.uberspace.de/screenshots/mejpee0fxi_(2013-04-05_15.34.41).png

* clicking on the edit-link for a property sets the focus in the wrong input field and adding a qualifier is difficult when you are typing too fast: http://www.youtube.com/watch?v=WwQl_U1jYgI

* the tooltips are misleading for some properties: http://lbenedix.monoceres.uberspace.de/screenshots/d6iyzjfoz3_(2013-04-05_12.02.43).png

* the clickable area for hiding the sources is too wide, especially on touch devices it would be easy to miss the add-sources link and hide it by accident: http://www.youtube.com/watch?v=aMjmwljk2Kw

* the edit column is looking strange. I think you tried to make it look like one column together with the langlink-column, but that is not working well
* * there are the change-order separator arrows at the end of the langlink-column: http://lbenedix.monoceres.uberspace.de/screenshots/lwdb47hk6h_(2013-04-05_01.11.11).png
* * and there is a lot of white space right to the edit link:  http://lbenedix.monoceres.uberspace.de/screenshots/gu8dxbp5g7_(2013-04-05_01.06.23).png
* * I think it would look better when the edit-column is separated from the langlink-column by color and the text should maybe right aligned: http://lbenedix.monoceres.uberspace.de/screenshots/gy3icgq1qa_(2013-04-05_01.26.08).png


I hope someone else who is more resilient than me would add these things to bugzilla.
