I’ve been a WordPress user for many years, and design and maintain my own sites. As a result, I’m not sure that many of your features will be useful to me, but I’m willing to try some of them anyway, to see what benefits may be available.
For instance: If I run a performance test (https://premium.wpmudev.org/hub/my-websites/?site_id=651626&tab_slug=performance#site-details-651626), and make all the improvements to improve my score, and decide not to continue past my 14-day trial, will all the improvements remain?
Thanks for your kind assistance. Tino
