Request for filtering (sorting) by update date

Since I can’t write English, I post it with the help of Google Translate.

Thank you for publishing a nice plugin. I use it conveniently on the top page of the site that I manage.

By the way, I wanted to make a request as a function, not as a bug, so I gave a message.

This plug-in has the following options for sorting: date published, most comments, title, and random. Depending on the site, the update frequency is high, and it would be very convenient if you can sort by update date.

Now with self-customization
flex-posts / includes / functions.php
Inside, we are adding conditions by query and adding condition options on the form so that we can sort by update date independently, but this option is planned to be added in future versions. Will you do it? ?

I think that there are many people who find the option of sorting by update date convenient, and I myself would like to continue using this plugin for a long time, and change the program source every time the plugin is updated. It’s hard to do, so I’d appreciate it if you would add it.

We apologize for any inconvenience, and thank you.
