It would be nice to have a UI option in IP addresses to choose which NIC to use for inbound/outbound.

Add possibility for mass management of Failed Request Tracing. To have option for administrators check for what domains it is enabled and disabling them "in bulk"

Add the ability to custom brand the Plesk footer links rather than just hide them.

Also add the ability to add extra links.

Branding is important.

When logged in to the panel as the Administrator, it is possible to switch between Service Provider and Power User views using a button in the bottom left corner.

However, this button is missing when logged in as a Reseller. It is still possible to switch the view via Tools & Settings > Interface Preferences, but it is not as convenient.

Please add the "Switch View" button for Resellers as well.

Currently hardware drive is not displayed under Tools & Settings > Server Information if there are no Plesk-related folders on the hardware drive.
It is expected to observe information about all HDDs in "Server Information" Item

Currently Plesk administrator is able to see active FTP sessions in Plesk interface. It would be nice monitoring feature to add if the same could be done with active SFTP sessions.

Suggested feature implementation would allow to create custom locales from panel interface. Including database in an implementation should secure custom locales from being overwritten during updates.
Client's business environment will gain in easiness of management and consistency.

Customers with international clientele would benefit from it.

Be able to customize/manually set the starting dates in the bandwidth calculation based on the initial plan billing date.

I.E.: If my customer plans is from (15 / november / 2020 - 14 / December / 2020), how can i set this dates in the bandwidth calculation for this subscription).

Currently it is possible to set notifications about "Whole" Disk usage of a subscription (mail, databases, web files). Yes, it is possible to exclude some units for calculating in T&S > Server Settings, however it would be great if customer/administrator received notifications about each separate resource overuse, that can be defined. (Mailboxes or web)

Kernel updates are excluded from Plesk update manager (https://support.plesk.com/hc/en-us/articles/115003708353), however, no notification about available kernel updates is shown under Tools & Settings > System Updates. It is necessary to implement such warnings so that one is aware of available updates and can run these manually via command-line interface.

For now the ability to forbid managing PHP settings is configured via permission in service plan. However, it is not possible to configure permission for some particular parameter (for example open_basedir). Please add this feature. There is already declined one with 3 votes https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/16470508-choose-which-php-settings-can-be-edited-by-end-cus

When I need to select several files or folders I have to select them one by one. Could you add a feature to select several files by holding Shift button, for example?

It would be great to add functionality/extension for such purposes, the same as for hosting plans (https://www.plesk.com/extensions/hp-exporter/)

Even if the default Theme is good, an own and custom Theme for the Panel would be for bigger Company's better and to make a Onboard Theme Customizer would it make it such simpler to customize the Panel.

Add the possibility to change the time format in Backup Manager as AM/PM is America standard and 24h format is European standard.

Currently, it is only possible to upload a file in "Tools & Settings > Branding > Logo" for the plesk logo.

Following 2 things would be cool:
- Possibility to use a URL instead of a static file (we have a fileserver with our logo, when it changes we can just update it there and plesk would take the new one automatically)
- Possibility to use a SVG as logo.

Currently this is not changeable, the logo is defined in /opt/psa/admin/application/default/layouts/simplified.phtml:

    <header class="page-simplified__header">
        <div class="page-simplified__header-inner">
            <div class="page-simplified__header-logo">
                <?= $this->logo(); ?>
            </div>

Ability to hide "Run a Command" option in subscription level Scheduled Tasks

you only have one list setting so its spanned over pages...be able to set a list view and remember it.

In the current Plesk version, the password reset page only asks for the email address. If a customer does have multiple accounts on the server with the same email address assigned, he will receive a password reset email for every single account with this email address.

If the password reset page would require the username too, it would be possible to send the reset email only for one account. Like in the old plesk version.

Make it easy to get to file manager instead of playing hide and seek.
Maybe a file count for each directory.
Use my 404 when I follow the instructions to do so.
