Currently, logs about create/Remove Directories or Files are only stored in panel.log with debug enabled. A feature for it will be appreciated in order to avoid enable debug into the server and increase server process.

The suggestion is to implement CLI utilities to enable/disable Plesk debug:

plesk debug -enable
enabled = on
filter.priority = 7
show.util_exec = on
show.util_exec_io = on

plesk debug -enable --sql
The same as previous + show.sql_query = on

plesk debug -disable

Now it is necessary to remember panel.ini path (/usr/local/psa/admin/conf/), copy panel.ini.sample, then edit it manually every time. And the same procedure to disable it.

Please add Mailman support to Let's Encrypt.

Ideally, one could issue either a certificate directly for lists.domain.com or a wildcard certificate for *.domain.com.

Furthermore, a secure connection should be enforceable.

Thanks!

Add support of TLS 1.3 to Plesk interface's web server. TLS 1.3. improves security.

Allow the ability to assign separate SSL certificates for multiple mail servers.

As you probably know, Let's Encrypt supports ECDSA certificates. Shorter handshake time, fewer data to transfer, faster page load time in the result.

I suggest Plesk feature - add option choose between RSA and ECDSA certificate when signing with Let's Encrypt.

Currently, it is not possible to authenticate on https://hub.docker.com/ to use the container located in private repository.
The w/a is to make the image public, download it and make it private again.

Add an option to exclude domains / clients / resellers from a backup to the Plesk user interface.

Currently, it is possible only via command line:
http://docs.plesk.com/en-US/12.5/advanced-administration-guide-linux/backing-up-restoring-and-migrating-data/backing-up-data/specifying-data-for-backing-up.68839/

This is all about security, it's simply not a fully developed product without this facility and I am hugely shocked and surprised it doesn't already exist.

Implement a feature that it will be possible to update a Plesk license on a server behind proxy or web application firewall (WAF)

Currently the Let's Encrypt Wildcard requires that main domain would be hosted on the Plesk server, and pass the HTTP-01 challenge as well as DNS-01 for Let's Encrypt.
However for issue the Wildcard Let's encrypt require only DNS-01 challenge.
The HTTP-01 limits the causing the issue since not always the main domain is hosted on the same server as the subdomains.

Add possibility to use repair kit extension under a reseller account

Include in Plesk a new feature to find out which Plesk login has created or restored a backup in Plesk. This could be done recording such logs in Plesk Action Log.

Add server-wide custom error pages configuration via Plesk UI.

Per-domain solution is her: https://support.plesk.com/hc/en-us/articles/213370209-How-to-enable-custom-error-pages-for-a-domain-in-Plesk

I think a call in pin would be nice. Something that the user can change, but it is kept hidden unless they are logged in and click on it to see it. This will allow for end users to request help securely.

It would be great to have the ability to add sets to existing WordPress instance via Toolkit. On most occasions when we place an existing WordPress site under management have have a pre defined set of plugins we install. These need to be installed one at a time or via script. A number of developers have also expressed ability to install their own sets to an existing WordPress instance.

Plesk should add support NFS Partitions for the vHosts as it would make it possible to over customers with High-availability clusters

Git extension: Add option to locally-hosted Plesk Git repository: listen for two or more Git branches simultaneously on the single Plesk domain.

At the moment, disable_functions do not work per domain in Plesk for Windows because disable_functions can be specified only in php.ini, not in .user.ini.
Plesk utilizes .user.ini for custom PHP directives only.

Please, implement support for custom disable_functions (and other functions that cannot be specified in.user.ini) on per domain basis in Plesk for Windows.

Thank you.
