I have wasted so much time loading plugins that, after an hour or more of trying, I realize they don't work. This has happened over and over again. There are also plugins that I am sure would work fine, but I can't figure out how to use them and there are no directions to be found anywhere and no support.
I would like to see good instructions for all plugins to be mandatory. I would like them to be tested before they are live, so we can be sure that they work.
I would also like to see mandatory free phone support for all plugins. They are making enough money off the paid versions, they can do it.
All plugins should be clear about what they do for free and how much it costs to get to full version. Sometimes they hide this information. Sometimes I feel baited. THIS IS UNETHICAL. WordPress should be a scam free environment. It is not.
