Two tiny things that make me choose Chrome
1. When I use <CTRL>+<TAB> in Opera in doesn't pick the next in line, but the last one you have used. Irritating.2. In Windows 7, when you click on the Opera in the <TASK BAR> i doesn't pop up. It tries to ask you which window you would want to use. Dont' like that feature.
Regarding your first issue, try the following: Opera Button --> Settings --> Preferences --> Advanced --> Tabs. The rest is up to you. Concerning your second issue, I am not quite sure what it is since I have Windows 7 and clicking on Opera in the task bar works just fine for me. Anyway, I gave you one less reason to not use Opera.
Hello are you talking about the opera thumbnail previews on Windows 7 taskbar ? Is annoying for me too, but you can disable it in Opera too 
Write the next line in Opera Browser, instead the link:
Uncheck the Use Windows 7 Taskbar Thumbnails box
