Useful but bad UI

Even the free version has a few useful utilities, but the app looks dated. I dont mind the new blue window pane (as opposed to the system default gray), but I cant resize the window, which is really annoying when Im trying to look at a list of items - the app occupies maybe 30% of the total available screen space (on my 13" MacBook). Also, the icon at the top of the window is very low resolution (aside from being unnecessary). These are relatively minor annoyances, but they generally lead me to the conclusion that the developer may not have been thorough in his design; therefore Im VERY unlikely to pay for this app in the future.
