A bit of an update on a feature we're working on right now that should make adding and updating themes and plugins a lot easier.
ProofBuddy 2.0 is dependent on server settings on whether it can install plugins and themes automatically, and most hosts aren't setup to allow ProofBuddy to do what it needs to do. And they're setup the right way. While it would be nice for ProofBuddy to have access to write anywhere it needs to, it's generally safer for a host to not allow that to happen.
With ProofBuddy 2.1 we're adding the ability to upload themes and plugins using your FTP login information instead which should make it easier to add new plugins and themes. ProofBuddy will also occasionally check for new versions of any plugins and themes you have installed and let you update to the newest versions automatically as well.
The goal is for this also to allow you to update ProofBuddy through this same process.
And here's an obligatory screen shot of the first step to installing a new plugin via the new FTP uploaded.
