Launch Base Beta Test

What are everyone's thoughts on this?

I think you should deactivate the "Install Plugin" button in case the plugin is installed and the version numbers are matching. Then you should add another info to the info box like "Status: Installed/ Not Installed/ New version available" or something like that.
Alternatively you can add a new button that replaces the "Install Plugin" button with "Update Plugin".

Little question: What happens if a user installs a plugin, then downloads a new version and installs this one - does LB remove the old files or does it try the remove the "new" ones?
