Integration with WHMCS, Cloudlinux and other resources
In my opinion, integration with WHMCS would be the icing on the cake.
The creation of packages for use in WHMCS is another improvement that Spanel can receive.
I just haven't returned to Cpanel yet because I believe Spanel can have a lot of future.
The integration with Cloudlinux is another improvement, since we can limit resources on account, even if one exceeds, the others are not affected.
Finally, being able to activate and deactivate PHP packages directly in Spanel was another very valuable feature.
