I am one of those who likes the full blown, everything option. Thus, unless I overlooked it, Would love to have one large Simple Press all inclusive plugin to upload.
Since they can be activated as desired anyway, why not have one that is a large single zip file with all the current SP Plugins. Since they still need to be FTP anyway to the resource folder.
So, I would just make sure to have created the SP-RESOURCES folder and under it the FORUM-PLUGINS, then upload the one big zip file to it and run the unzip option on my server.
The reason I would like to have one large file is because on my server, I am able to just upload the zip file to the right directory area on the server, then just UNZIP the whole file and usually it will create and put them in the correct folder. This would be a great time saver for those like me who just want the FULL PACKAGE anyway!
