Thanks for your concern again!
As you mentioned, relying on a plugin that cannot be updated seems like a problematic way to go with a paid, premium theme, that’s a valid point from your side. However we don’t have any plans to upgrade at the moment but we’ll keep that in mind to find the alternatives in the future release hopefully soon.
Regarding WooCommerce sidebar, there seems to be a bug associated to the theme, we just noticed.
We’ll release an update after fixing the issue and follow you back earlier by Next week.
Thanks for your feedbacks again. We’ll follow you back after the updates.
