I have been working with Apophysis for years now and have collected a lot of plugins, scripts & tutorials. Now that 7x has came many are useless. All dough Xyrus has recompiled many of them for 7x (x64) which are available here. The problem is still that there are tons of plugins to be added.
I know that there are a lot of problems with plugins. Many people still use old versions of Apo (especially v2.08 3D Hack) and there are a lot of old plugs that are made for this old versions.
My idea is to form some kind of plugin repository for each version of Apophysis. That way It would be easy to maintain sources, versions, port old ones to 64bit, see which ones conflict with one another, etc ...
It would take time and effort but I think that would be a great solution. Better than browsing all the existing packs & finding that the plugin you need is not there, or doesn't work for your version or is conflicting with existing ones. And what about Apophysis Plugin Manager? Where is it? I have an old version. That tool was a solution in a way but you still needed to be careful which ones you add.
The repository is one solution. The more sophisticated one would be to add some kind of plugin management system in the program itself in future releases. Like in Processing 2 where you have a library manager with which you can instantly install any library, tools and modes that are available in the repository. That would spare a lot of time searching for a specific plugin you need that moment.
