With every update so far I went to the routine of deleting the "defaultpartnercontent.json" to get rid of the default search engines (which I never use) and get my custom engines back.

This no longer works. If I do that, Opera whines that a file is corrupted, and won't launch.

I don't want Yahoo to use the "y" shortcut, I want YouTube. I don't want the French Wikipedia on "w", I want the English one.

So is it possible now?
