It would be nice to have possibility to add comment/note to a service plan.
Since plans have to be created for every reseller, it would be nice to have something that could signal that it is the same plan on another reseller.

I use magic spam pro as plugin and it shows underneath the system information on the start page. That means if I want to start the plugin, I have to scroll down because the system info takes quite a bit of space. It would be nice to be able to customize the appearance of the start page / dashboard, i.e. what information is displayed and where.

as mssqlplanner.com provides their Several analytic report free
like Space analysis, DB level analysis , CPU, RAM , Query level

It will be worth to customer to have such report to see how is database server performance now and they will be able to know when they should buy higher resource with big rock

To let the extensions log/note the actions in the Plesk's action log.

As of now, on any extension, a user can do any action without acknowledgment of what has been done.

For security purposes, it is desired to know what actions has been done in Plesk, and installed extensions.

Due to security reason users may need to ability to protect their archives with password. Currently there is no ability to extract or create such archive. Please, add

For now the database server assigned to the domain via service plan is used to host WordPress database. Would be nice to add ability to choose other database servers if exist as they might be more suitable for customer needs.

When a MSSQL database server is upgraded to a new version, the name can not be changed from within Plesk and it needs to be done manually into the Plesk database once the name is set on MSSQL side.

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/ngx_http_js_module.html
http://nginx.org/en/docs/njs/install.html

It would be nice that you can sort on 'Valid to' with in the advisor section secure websites with ssl/tls certificates.

Like the wp-cron feature released recently it would be useful to have other functionality like
- Warn if not using InnoDB
- Clear out and limit post revisions
- Disable revisions
- Cleanup autoload options
- Cleanup sessions
- Image crushing

At the moment only under admin username is possible to log into the Plesk Repair Kit extension using the link:
https://server.example.com:8443/repair/

Add the possibility to log into Plesk Repair Kit extension under Additional Administrator Accounts that are created in Plesk > Tools & Settings > Additional Administrator Accounts

With current version, to get all subscriptions that will expire soon must request all subscriptions, include the limits dataset, and then perform a filter.
Leaving the possibility to filter by expiration date will be a greate improvement.

Currently, restored backups, which have been downloaded from a remote storage, are being stored locally and appear in the backups list and become part of a backup process.
Expected behavior:
Download, restore & delete downloaded backup files. Remove from the backup list.

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.

Allow the Pleask user to specify a mailbox with no (zero) capacity for the purpose of managing email from a 3rd party such as Gmail. This would allow email to be forwarded to Gmail without the exceeded capacity error but also allow Gmail to send mail through the mail domain. Currently this needs to be modified by admin and it's hard to explain each time to the admin.

Limit the FTP Access to a specific IP range or IP for a specific subscription:

Ex:

Example.com / IP 10.0.0.1 allow only connection between 10x to 30x IP

It happened to me a few times that I had to create a bunch of mails, over 100 mail accounts. I'd be really nice to have an "add another" button on the bottom, which saves the new account, but reloads the page so you can add another. A minor feature, but think it could make someone's life easier.

Cheers.
