Net core can run applications on windows and linux with a short configurations . Please add support to both OS

At this moment you can change favicon.ico by replacing /usr/local/psa/admin/htdocs/favicon.ico, however it will be replaced on Plesk update.

It is also not possible to make it permanent using custom theme from Plesk branding guide.

Please make a way to customize favicon.ico on permanent basis

Free version of Enterprise Litespeed, it would be nice to use lsphp+Openlitespeed+LSCache (free) within Plesk.

add the ability to manage auto-reply option Domains > example.com > Mail > Email Addresses > Auto-Reply > Send an automatic response to a unique email address no more than (times a day) via API.

add HTTP/3

It will be good if Plesk can implement automatically applied wildcard let's encrypt option by default.

The actual MailQueue status is useless, becaus the "status" of the email isnt viewed. This contains the important information for mails with problems.... Please expand it with the status, like it is done win Webim for example

It would be nice to have ability to prevent client from modifying the number of maxchildren . The permission "Hosting performance settings management " revokes this but it also prevents the user from changing PHP options like execution time and maxvars. But we would like to allow our clients to manage "Performance and security settings" parameters in Plesk.

Plesk Obsidian introduced the Dynamic List View Mode and some of our customers are having problems understanding the new GUI.

It would be very helpful to configure the View Mode at the Service Plan level:
- Disable the possibility to change the View Mode
- Configure a default View Mode

Be able to synchronize Plesk notification settings between servers.

Add mcrypt module to Plesk PHP 7.2 and newer.
For previous PHP versions it's included out of the box.

Mcrypt 1.0.2 natively supports PHP 7.2+ (https://pecl.php.net/package/mcrypt/1.0.2)

It's, for example, required by Prestashop 1.7.x, which is quite popular among Plesk users.

Currently, management of additional Apache/nginx directives is available for Plesk Administrators only.

With Apache, it is possible for users to add custom directives via .htaccess file.

However, when running a Plesk server with nginx only hosting and a large number of customers, it takes a lot if time to configure nginx directives manually for each.

It is clear that additional Apache/nginx directives fields are hidden from Plesk users for security reasons, but it would be great to have an ability to enable this feature at your own risk.

Implementing the new standard WebAuthn would be the best solution for 2FA.

Plesk PHP handlers should have the latest libicu package version for better compatibility with newer versions of web apps such as Magento

A a reseller I would like to be able to create my own specific plug-in 'sets' for my WordPress customers. Normally this should be done at this level, not by the 'top level' administrator.

Maybe it is possible to use the same tab and visualize created sets from resellers with an icon.

Add option to disable/modify appearing pop-ups about task execution or applications installation.

Please make the panel.log file available to view in Plesk GUI.

It would help in troubleshooting issues that show no warning or error messages in GUI, and provide a way to investigate issues if SSH access in unavailable for some reason.

To allow Plesk to work properly with multiple browser tabs under the same user session.
For example with Google Chrome, log in once at Plesk as a dmin then:
Ctrl+Click on Tools&Settings, and then also on Clients
On the clients page, click on "Log In as Customer" and wait for it to load.
Go to the other tab (Tools&Settings) and click somewhere. It will be automatically redirected to Client, instead of staying as Admin for this tab.
