I created an account on these forums just to add to what has been said. I love CCleaner. I also appreciate the performance update in version 5...really noticeable. Having said that, the interface looks very very poor imo. I can understand your reason for updating the interface however it was done in the wrong manner. I hate the metro-ish look, the top white titlebar, the caption buttons, pretty much every GUI element changed. And I am one who like minimalism in application interfaces. However it doesn't work for CCleaner. I doubt you guys will bring back the previous interface however here's my two cents. Simple solution: - Allow users to switch themes including a classic look which most of us love. Thank you Piriform!
