Great job, Dave, this cleanup was really needed.
The problem with free plugins is that they discourage new versions.
For example, the Skeleton plugin. All of us who make plugins have started there and it's very clear that it's a very basic version, badly documented and there are things that it doesn't have, like the whole mobile version part among others. Groups and Forum also deserve an urgent review.
The prices of the plugins... Most of them are cheap, look in other similar stores:

I think that besides cleaning the antique shop without technical support what we need is new users. I understand that OxWall.com has abandoned us because we do not bring them any benefit, perhaps the solution is to modify the economic conditions of the store and that a percentage of sales would go to OxWall.com and thus put us a more attractive cover. Maybe 20%, I would not pass it on in the prices because I am an amateur and I do not live from this, but I would understand that other developers do. If there are new users there will be sales, currently there are not, you can see that there are no questions or doubts about new installations in the forum.
