A section under settings (available from the dashboard) to place basic client notes. We have some clients who use third-party services or there was a specific reason why we used certain fonts, custom code, hid certain elements on different devices, had trouble with form submissions so we did XY or Z to correct, etc.
It'd be great to be able to note a few reminders for when we come back to projects to make updates/changes.
A place to add editor notes on page Sections seen on the back-end but invisible to the front-end. I use VS code, as well and I like the fact I can add notes. Then when I have to go back to a client site I can review the notes on the section so I know what I did and refresh my memory.
