What's the motivation behind the export? Ah, I see this fixes #34.

I also think the error needs to be more explained, "permissions" isn't very clear by itself. This information is already available on the website too, so I'd rather just somehow link to that instead of inviting people to discord.

Maybe you want to make a separate PR for these two things? It's better to keep them apart instead of mixing things up.

Ok, I added a button that shows up on the plugin page when it fails to install that will take the user to the troubleshooting page and I will move the export to another PR

Thanks! Hmm, just showing a button might not be the best UX. Perhaps we should make this a modal dialog instead?

We may also want to have some different error handling: a file being 0 bytes is probably not the only failure state that exists. Maybe the engine should throw a script exception if Meta::LoadPlugin fails, and then we handle that and display that error specifically more prominently.

It might not be the only error but it's certainly the most common that we have to help people troubleshoot in the discord server frequently. A file size of 0 also includes a missing file.

As for a dialog, I'm not sure of a good way to do that.

bump, though I haven't given much thought to a dialog since pushing this

This is less important as the permissions thing should be mostly solved in coming updates. Without a dialog or anything more specific I don't think I am ready to merge this as-is.
