Password protected directories feature works only with Apache-based websites. Please implement the same feature for nginx-based websites

assign different IPs to subdomains. In the current system, only the IP address of the main domain is assigned to the subdomain. Big deficiency.

When a domain is removed from Plesk, all corresponding data is removed as well. However, due to government laws, it is needed to keep access logs for a year, even if the domain is removed from the server.
Please add some option to keep such logs.

An option that allows files from a specific directory to be shown in browser as source code, HTML, PHP, SVG etc

Compile sw-cp-server with httprealipmodule.
It is useful when Plesk itself is behind a proxy.

Example use-case: redirect clients from WHMCS to Plesk when Plesk is protected by CloudFlare

Need to adding the certificates with Let's Encrypt for the domain names added as serveralias in the apache directives on subdomains, with autorenew system.

IIS has CPU management based on Application pools.
It would be great if memory was also controllable.

it would be nice, if you can put little Question Marks between the important words, so that you don´t have to read the whole book with tips.
Over these Question Marks you can hover and than there is a short information about several steps.
Sry for the bad english i am from Germany.

Currently only two IP addresses can be assigned to a domains in case they are IPv4 and IPv6.
It will be great to assign several IPv4 and/or IPv6 at once.

Please add one more feature in Plesk Panel. in Create User Role page please add website selection drop down so we can add each user manage there own site.
Please add multi select drop-down so it will be ease for single user have multi sites.

Please pay attation for the next releases:
https://plugins.roundcube.net/packages/johndoh/sieverules

Maybe you can use:
roundcube/managesieve (default plugin)

A Script for Gameserver Hosting was cool

Currently, this can be enabled in IIS > example.com > Error pages > Edit feature settings

or Domains > example.com > File Manager and adjusting the web.config file manually

The native functionality to enable/disable detailed errors in Domains > example.com > IIS Settings will be easier for customer. Without involving server administrator or adjusting web.config manually.

Please add Fastly CDN support

in file manager, when dealing with images, it may be a good idea to put an option to switch to thumbnanil view

It would be great that you'd provide Nginx with the module ngxhttpjs_module already compiled.

We have some websites using NJS scripting language and we cannot running them on Plesk without modifying the code:
http://nginx.org/en/docs/http/ngxhttpjs_module.html
http://nginx.org/en/docs/njs/install.html

The screen says that the web stats will need authentication with ftp account. However this is false because only website owner can authenticate for the web stats. So my request is to really accept ftp users as being able to view web stats.

A developer which has pushed his code to his git repository in plesk (through Local repository on your workstation funcion) is only accesible through authentication. That's OK.

The developer is ready to make his code publicly available.
Unfortunately that is not possible but it would be a nice feature to have.

Maybe not to use the same private repository, but likely in a way to clone it and make it anonymous available only with read acces through http(s) , ex. https://<url>/example.git

Currently, when the website is copied a notification is sent to subscription owner of the target website.
It would be good to add functionality to disable such notifications or change the recipient mail address.

Please provide a Best Free Compression Tool/API for all types of documents like image/pdf etc as a service for website development.
