I tried 15 twice and deleted both times. I have just installed 18 and it is currently pointlessly grinding away at something. I adjusted process priority so that I can still get something done using 12.16.
The reason I use Opera is because it has been a good tool for doing a pile of work. I have been able to make versions up to 12 into whatever finely tuned tool I require to hunt for, manipulate and use information. 15 to 19 are just useless toys copying the toy-town small-minded needs of dumb Americans and their imitators.
Get a grip Opera. This is a European product so it should be aimed at a higher intellectual level and properly marketed as a tool for doing proper work but still with the features needed for a chill day.
Maybe you could have it install in internet-for-dummies mode and have a big button in the corner that says 'north european mode' that loads the features that have made Opera special during the last decade. Then, for those who don't require that level of sophistication, the button for changing back is marked 'internet-for-dummies' or 'north american mode' or just 'dumb-ass'.
Otter may provide a solution but I share Staross's concern about this being a small and unsupported operation. Otter could disappear quicker then it has appeared.
I don't suppose there is any chance that Opera could get together with Otter?
