1. On the Free version, it's updated last month but the Pro version on your website mentions "Last update: 2018-10-12" so is your Pro plugin maintained regularly?
2. On the Free version, I don't see any "toggle" to switch between Monthly/Yearly prices. Is this feature available on Pro version?
3. If the Pro version has toggle feature, can it provide more than 2 values types of plans (for instance, Yearly / 2-Years / 3-Years) ? Example like this : https://www.jeriss.be/formules/
4. Your Plan "Unlimited Sites" still mentions a limit of 100 Domains. That's inaccurate marketing. Please clarify whether it's unlimited or limited to 100 sites.
