I just recently switched from Chrome to Opera and while I am loving the browser and it's features, I think it could be improved with very simple updates.
I use Opera 45.0.2552.881 on Windows 10 and OSX.
Update the browser so that when it's Maximized on Windows, there's a bit of space between the tabs and the top of the screen so that moving the window is easier. Right now the only way to move the window when I have a lot of tabs open (which is pretty much all the time) is going all the way to the right next to the + sign to add another tab.
On Chrome I can manually copy a password from my saved passwords. I like doing this when I need to re-login to an app in my computer that uses the same login information as the website version. This is not possible in Opera. I can't copy passwords and I think this would be a great addition. Also, seems like copying passwords or licenses overall in Opera is not possible as I've tried several things and didn't work. I don't know if this is a security thing or what, but it's kind of annoying.
I love the Speed Dial (SD), it looks and performs great. The only problem is that if I drag a bookmark from my bookmarks bar (BB) to SD then the bookmark disappears. Some websites that I use a lot I like having on my BB and my SD, so having the Bookmark disappear is really inconvenient.
When using Opera on my Mac, I am able to hit cmmd+shift+B to hide/unhide my Bookmarks bar, but apparently there's no way to do this via keyboard shortcuts on Windows? This should REALLY be implemented.
