You might recall that, several months ago, I went a little nuts about the iTunes 7 UI. To this day, I stand by my complaints, though I freely admit that my tone could have benefited from some moderation.
The ThinkMac blog (which, by the way, posted their own gripe about many of the same things I objected to) observed over the weekend that several of the most glaring inconsistencies were tidied up in iTunes 7.3. (For those keeping score, these are gripes #2 and #4c in the original dissection, plus the subsequent discovery of the impossible-to-hit pane resizer.)
Thanks, iTunes UI team!
