I don't doubt there's plenty of performance, and bug fixes, but The new icons to me just blur together when I look at them while the old ones don't. I understand the reasoning for the change, or at least as much as one without software creation knowledge can understand, but the combination of the fact I dislike simple/metro-esque design everyone is turning to these days, as well as the previously-stated fact the new icons just blur together for me prevent me from really being able to use the software as effectively as I do the older variant.
I've asked my questions, and have been answered, which I thank greatly for, and I won't be demanding any features be added on my behalf given I'm in a very miniscule minority here. That said, I'll be sticking to 4.0.14, and will understand that prevents me from getting any software assistance, though I haven't had problems with it yet, thankfully aside from chugging with larger image sizes. Thank you for the input, and I apologize if my reasoning seems petty for not using the newest release.
