Thanks so much for the feedback. I will start implimenting your suggestions ASAP.
1. Make search-box results go away by clicking anywhere outside of the results list, will be fixed next update.
2. Permalink is 6th button to the right of the search box, the curved arrow.
3. Yellow highlight is part of timbones' update in WME Color Highlights v1.3, I'll see if there's a way to turn that off, optionally.
4. Tooltips will be added next update.
5. Will add that as well -- you can still see your info behind the side-panel, if you hide it, as well.
I'll add screenie to original post.
