to the /wp-content/plugins/
directoryWhile active the plugin relies on the Suppliers Product Attribute. If this is not present, you will receive a warning until you create it.
As the Plugin registers order statuses, on deactivation these statuses will no longer be displayed in WooCommerce. Before deactivating you should re-assign existing orders to a standard order status.
No, if you temporarily deactivate the plugin you may notice missing orders, but they are still in the database and the queues/statuses will reappear when the plugin is reactivate.
You can update each orders (post) status via the database. Because this is a more advanced topic we won't cover exactly how, but it's pretty easy. Make sure to take a backup before editin database entries.
You can update the slug via Product>Attributes>Suppliers> But before doing so you should re-assign any orders using the existing slug to another status.
Again it's not a major problem, either change the slug back, re-assign orders, then update it again. Or, you can update orders (posts) directly in the database.
