What happen when client use my key to install for others? How can i prevent that???
thanks

The key disappears right after you click on the activate button. So, there is no way your client can copy the key.

There are ways without seeing the key you can install to another site what happens in that scenario also even if you hash out doesn't mean they are not visible unless your dashboard allow us to handle our keys and it is a bad practice if we remove a key from our clients site the site should not break only the thing shouldn't work is they updates.

Thank you so much for your feedback. I have shared this idea with our system administrator.

Are there plans to enable us to manage the sites where the licence is enabled?

So we can control which site gets the licence and which is disabled?

It will help if we have multiple versions of a site for client to view before they confirm which design / site they want. I have had at least one experience where there were 3 or 4 versions of a site in concurrent development before the final was selected and deployed.

The plugin works fine without activation. So, for now, we are encouraging everyone to use the license only on production sites.

We do have plans to add license management to our site but I don't think that's possible this year given the situation.
