Which Cura Plugin to install for J1?

I’m sure I am behind on this topic. My patience and attention span to do proper research as I get older dwindles lol. So I just realized there are three Snapmaker plugins for Cura. Snapmaker J1, Snapmaker, and Snapmaker 2. I have all three installed and keep them updated. Is this a problem? Are all kept up to date or are any obsolete? Will they interfere with one another and cause issues? I also found the Github for the Snapmaker plugin. When updates are submitted to the Github page, are those updates automatically applied to the plugin through cura when the plugin itself is updated? Or do the files need to be downloaded then placed in the proper folders? Also what plugins are you all using in Cura? Any fixes yet for changing color/extruder with scripts?
