For example, at the top screen space is wasted by a menubar and a tabbar that you almost never use, except for the "search" tab, which acts like a button (very counterintuitive). It is also completely superfluous considering there is a "back to query" button already. The statusbar below contains only one item I use much: the green/red connection indicator. The orange "Only search results with a [lock icon] are ..." is wasted screenspace: if you've seen it once, you've seen it forever. Then there are those rarely used non-standard upside-down tabs below the search query that are very rarely used and interact counterintuitively with the search type buttons, which really should be radiobuttons anyway. Then there's the "magnetmix.com" button. What does it do? I don't know, it seems to launch a browser window, but whatever it does, I don't need it. At least not often enough to warrent a permanent button. LimeWire needs a thorough UI overhaul.
