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

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.

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/)

On any Plesk server 18.0.29 has been installed by default recently (ie fresh install), Plesk has been enabling backups by default to run every night. We can't see any notification of this change of behavior in the release notes. It should be possible to decide to enable backup on initial Plesk installation as this of course uses significant disk space, this has caused us considerable disruption and cost.

Currently, Users are linked to Customers, but the menu to manage Users is located under Subscriptions.
No matter what subscription is selected to view users: in Plesk > Subscriptions > example.com > Users tab all the users of the customer are shown, no matter to what subscription they belong.
Please review the behavior of the Users tab: move it to Customers (Plesk > Customers > John Doe > Users) or show only the users that can manage this subscription under Subscriptions > example.com > Users tab.

In Plesk Onyx, there was a Server health widget in the home page, but in Obsidian it's no longer available because Advanced Monitoring + Grafana doesn't include this feature.

This missing feature in Obsidian was really helpful because it allowed to understand the server status on a first sight, this widget was showing clearly the status of the CPU, RAM, Disk, Network and Service with representative colors.

Please add flexibility on Tools & Settings > Notifications management: how many messages should be sent and how often. Currently notifications like Subscription expiration warning are sent every day which may create additional load on particular mail box.

Currently in Tools & Settings > Branding it is possible to change logo for both: login page and top-left corner.
It would be nice to make the feature more flexible: separate logo change for login page and for top-left corner

Ability to remove or hide the "Feedback and Survey" section which appears with the Dynamic list enabled on a new Plesk installation.

Is it possible to change the language? it Does not appear in a different language than English.

We need to place a custom button in the Right Sidebar menu in the Customer interface, however, this option is not available in Tools & Settings > Custom Buttons > Add Link Service > Location drop-down menu selection.

As for now, this location is only available with a custom extension: https://docs.plesk.com/en-US/obsidian/extensions-guide/plesk-features-available-for-extensions/implement-ui/integrate-to-plesk-ui/add-custom-buttons.73624/

Allow you to cancel a git pull as when you pull it now it gets stuck if it doesn't error out

It would be nice to provide access to users via ssh only to GIT.

Provide an option for Additional administrators to access specific subscriptions. This can be achieved by adding the subscription selection option to the Restricted Mode settings.
