On the top right in the header there is an help icon with a "help menu" which contains use full links to documentation. It would be great if administrators could add custom contact details to this little help menu for their customers/users to see.

I've added a mockup image to clarify.

Plesk's 'plesk repair fs' utility detects that folders do not exist, however, it fails to recreate them inside '/var/www/vhosts/system'. A new command or adjustments to the current command should allow recreation of such folders like 'example.com/logs', 'example.com/conf'. When manually created, files are created by the repair tool.

Be able to 'view' the PDF content via the File Manager view/editor.

Please add command-line arguments to Plesk' reconfigurator.exe to represent functionality that is available in the GUI.

For example, it is not possible to change MySQL Data location on the command line. This is unfortunate, as the GUI is pretty useless automated deployments.

I need to host one application in www.example.com and another application in example.com as if they were two different domains. It would be nice if Plesk would allow an option to create such domains and not reserve www as an alias for example.com.

I have 100 domains and next time aLOT MORE.
It would be VERY HELPFULl if i could have Categories for all domains for a better overview and workflow.
For Example:

• My own Domains
• Shop
• Wordpress
• national
• europe
• international
• B2B
• Holiday /Vacation
• ...

i cannot determine if a zip file extraction is running or when its finished

Customer is using add-ons to expand the disk space of his customers. Unfortunately the add-on does not allow to expand the "Notify when disk space usage reaches" limit as well. As the result, the reseller customer receiving emails, that the disk space is approaching or already exceeded the resource usage limits.

Is it possible to add the "Notify when disk space usage reaches" and "Notify when traffic usage reaches" to Add-on's settings?

Restrict or enable the manage trash.rotation settings in Plesk by user.

For example, when the settings are enabled, they are enabled globally and every customer/subscriptor whereas it would be helpful if it could be enabled only for admin.

If you have more than 100 domains/subdomains in Plesk, then the dynamic list of domains, which is loaded just after login, takes too long to load.

In some cases it reaches the timeout limit. It would be nice if after some seconds the page isn't loaded yet, then enable the classic view and reload the page.

Add a check to the amount of inodes before domain creation in order to avoid domain creation without hosting if the inodes are not enough.

At the moment if there is not enough inodes the domain is created without hosting,

Add an option in the service packs or other allowing a reseller to add a reseller it is the concept of the multi-level reseller (master reseller etc).

While I am working in File Manager's Code Editor, there seems to be a static session time-out. Even if I am saving my progress periodically, the session time does not reset. This may be the result of settings that my shared hosting service have put into place, but Plesk should reset the session-timout while I am not idle and using the Code Editor.

It would be very conenient to be able to manage the subscriptions' scheduled tasks via CLI.

Add ability to disable email notifications about successful Plesk updates, and anacron (daily, weekly, monthly) tasks using Plesk panel.

Add ability to change http/https port for one domain

It would be nice to have an option to insert a custom URL value under the Plesk logo at the login_up.php page instead of the harcoded Plesk login url value

The action log should show information when clients disable the Web Application firewall (ModSecurity).

Use passwordless or MFA on all service.

Strong passwords are key when it comes to internet service.

Many password resets information is sent to an email address. Access to such critical account should be protected with either passwordless or MFA functionality. A hacked email account with username and password is a golden ticket to steal the identity of customer/user.

Instead of or in addition to Phusion Passenger add PM2
