Plugin not show alternate suggestion

The plugin does not support suggestions, it has no domain name generator.
To divide the results into two columns you could change the CSS to something like this:

.wp24-dc .table-row {
    display: block;
    width: 50%;
    float: left;
}

I’m sorry, but that is not possible. Only regular links are currently working.

Where should this prefix and postfix text be added? To the input that user writes into the search field?

I could add a prefix and postfix option that will be automatically added to the domain name. So that those alternative domain names will also be checked.

For example:
Prefix: the, my-
Postfix: -master, 24

User searches the domain name “wordpress.com” and the following domains would be checked:
– wordpress.com
– thewordpress.com
– my-wordpress.com
– wordpress-master.com
– wordpress24.com

Would that be a satisfying solution for you?
