2- Add option to disable/enable emails from Virtualizor for different actions. For example I dont want to send email when their service installed or suspended, but want to send email in case they used for example 80% of their bandwidth or once their vps reinstalled successfully. This can be added to configurable options, so the admin can choose what emails to be sent for each product.

3- In Virtualizor, in vps statistics ad another column to show the used BW, it was in Virtualizor but removed after recent updates.

5- An option to sell backup options as addon. For example daily, weekly or twice a day per vps while the customer is ordering. Currently there time intervals are limited and you can set specific settings for specific vps (and the number of back up to be kept per each vps).
6- In a ticket I requested to integrate a firewall such as pfsense to Virtualizor, as a vps, if possible.
7- An option to monitor the IO per disk/storage and alert admins in case of any issue.
8- Auto update the VPS statistics page, specially for download/upload column.
9- Option to choose the number of concurrent backup process + starting the next backup once the other is being uploaded. The system is free once the current backup is being upload, so why not making the other backup ready to upload? In one of our server making backup of 13 vps with average size of 30 GB storage took 1200 minutes!
