Why isn't this a thing? There's no reason to make mod-authors have to re-upload their mods to be the main file. This needs to be changed so I can set my main file after uploading. It would also be nice if I could pair mod files to versions if I have multiple files that need to be downloaded together, without having to make a whole separate project page. Ridiculous.
Are we ever going to be able to set the main file manually? Seriously... what the heck?
