Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

It was a little tough figuring it out at first, but it seems to be doing exactly what I want it to do. In the sending and returning process, I think it could be done with perhaps fewer steps

In the Preview app on your Mac, open the PDF that you want to password-protect. Choose File > Export, then select Encrypt. You can also enter a new name for the PDF if you want to create a pass worded copy and keep the original PDF unencrypted. Type a password, then retype it to verify the password. Click Save.
Folders can't be directly encrypted in macOS, but you can put them in password-protected containers. This has the effect of protecting your folders and the files they contain with a password. You can password-protect folders on macOS using the built-in Disk Utility application or a third-party tool called Encrypt.
Make sure in Preview > Preferences > Images “When opening files:” “Open groups of files in the same window” is checked. Select all the files you want to merge, right click on them and choose Open with Preview. At this point you have to convert them to PDFs. “
In Finder, select all the images you want to include in the PDF. Right-click (or Ctrl-click) one of the highlighted files and select Open With → Preview in the contextual dropdown menu. In Preview's sidebar, drag the thumbnail images into the order that you want them to appear in the PDF document.
