Thanks for building such awesome control panel, it's really powerful and nice at the same time.
i think following stuffs will make this panel more user friendly.
1. Single user multiple database manage system, for example one user will be able to manage multiple database also there will be a menu with user permission setting. Due to lack of this feature we cant import cpanel website which has multiple database with single user.
2. auto letsencrypt ssl generate and renewal for all hosted domain
3. softacolous integration
4. cloudflare integration (plugin)
5. Email Delivery Tracker ( Like cpanel )
