The opera Blink looks indeed like Chrome. I hate Chrome so I'm gonna leave Opera Blink for what it is. I tried to get something from my v12.2 to v19 like you suggested. But it didn't work. Let's forget all about it. I'll remove the v19.
Now with the v12.2 already installed how am I going to proceed to make it look like my in the meantime overwritten v10 ?
I have a previous copy of my v10 on a clone BU HD disk and a normal C drive backup. What do I have to import from my previous v10 to my actual v12.2 to make it look like (themes, buttons and extensions only I suppose) my v10. The history and bookmarks don't have to be imported of course, since the transition went smooth from v10 to v12.2. It's just the looks are too different and a bit messed up.
