I've waited with opera 12 awaiting for you to mature your new product. More than one year, but now is aging,constantly crashing because it is increasingly incompatible with new operating systems (windows and os x).

The "new" opera strips a huge amount of the functionality that matters. To name a few :

1. Open any bookmark file: hence manage completely separated bookmarks for several projects. Otherwise size grows unmanageable
2. Sessions
3. Arrange tabs
4. private tabs
5. mail (now somewhat solved)
   ....
   But for me, the first is a deal breaker.
   I have been promoting your browser since version 3.5 to friends, family, coworkers. At those times, it was amazing it was only 1MB. Now, I've stopped the promotion at all.

I understand you decided to reduce costs and maybe receiving funds from google. But now you are a "me too" browser, only alive because of your brand recognition and history. Hope it will last until you realize what you are doing. Recall "Blackberry"
