Opera 18 full time
I finally decided to retire Opera 12.64 for now and give 18 the full time treatment. The only way I am going to know if this is going to be my daily browser is to use it more than occasionally. Loading the bookmarks from 12.64 wasn't hard but wasn't easy. I was able to duplicate what I had in 12.64 including folders to opera 18 (big concern). It took some time and was a reason I probably hadn't started using 18 sooner.
So far I like it. I wasn't impressed with opera 15 but knew over time it had to get better. The browser is much more stable and faster than 12.64 in my case.
Some of the feature requests I have seen echo my own requests and hopes so hopefully those will be included in future updates.
