No no no. This is what I have said last year, people typically click next next next, without reading what's on the panel. Remember I advocated to have all plugins installed by default.
And I think the user is right not to read all those panels, this should be easy, not geek oriented ;-)
So yes, if people would read everything nicely, they won't have a problem. But I still feel it is just our fault, we should have made it easier.
It's like : if the user can use your interface the wrong way it is not the users fault, but yours ;-)
So I hope in the next release we will install all by default, and only for those geek experts allow by extra clicks to (de)select appropriately.
