Please add a way to manage the sieve rules (server side mail rules) in the user interface (and not only via roundcube webmail)

Currently, in Plesk it possible to change IP only on subscription level. As a result, the IP is changed for all domains under subscription. The ability to change IP on domain level would be very useful

Currently, "Subscription expiration warning" notification is sent per subscription.

The feature to manage notification with all expiring subscriptions would be very useful

The ability to re-synchronize data upon migration is great.
But when you are migrating a dozen or a hundred domain, it is painful to click re-synchronize on each domain one by one.

Please, add a button allowing to re-synchronize all domains at once.

Thanks

Add possibility to disable permission for editing My profile for customers' account in Service Plan, therefore customer will not be able to go to Plesk > Account > My profile

When the user tried to delete file(s) via "Files" tab, it says that:
Are you sure you want to permanently remove the selected files and directories?

There is no information about file name and selected file numbers.

So the users may not sure what they delete.

Show file name and selected file numbers before deleting.

if there are thousands of files in a folder it takes too long to load the list..

This will meet your motto "Plesk. Being the only OS agnostic platform" :)

When I got message

Warning: Another user with the same username (admin) is already logged in to Plesk.

it is good if it has link to check accessing list of the information page.

When Service plan is changed and synced to subscription, custom settings for very subscrition should be marked and if you want to preserve you check them or cancel them if you do not.

This way is more transparente, what can you loose or miss when you are changing Service plans and syncing.

Min. 95% of all users and clients do not logout from Plesk panel correctly.
They only close the site - which causes unnecessary processes, - and security problems, e.g. when users do not logout in internet cafes or similar.
Please realize a good visible logout button!

There should be a checkbox to set active/passive/both mode of connection and ability to set passive ports range directly in Plesk.

It would be nice to have a simple listing of the last 30 days or so history of System Updates and Extension Updates. Currently when Plesk updates System components or extensions automatically, we're left wondering what was updated, unless we dig into the server logs via command-line. Thanks for all your hard work BTW.

Our suggestion is add an UI element to user area, where end user can change preferred outgoing ip for domain - ipv4 or ipv6. Without mail server config hacks from server admins.

i saw a webpanel called centos web panel , has a ffmpeg installer , it is click here and voilà ffmpeg is installed.
that will be some wonderful addon as most servers now have sites with videos

Plesk now include cron job format , but with inputbox.

Please something like WYSIWYG

Sample: http://crontab-generator.org/

When adding a new subscription, the value for IPv6 address is set to "none" even if the server has assigned an IPv6 address (and other domains already use it).

It's time for Plesk to enable IPv6 by default for new domains, the same way it does for IPv4.

My suggestion lies on the fact that I indeed lost my work on a php file that was open in the code editor, when I absent-mindedly pushed the "Apply" button on the text editor and realized with horror that my admin session timed out and I was returned to the unmodified version of the file once logged back in.

It would be convenient to autosave in the background ongoing changes of a text file that is bound to change once opened in the editor, in order to prevent data loss.

Add description/comment field to trusted ip address on fail2ban
