Process Markdown Automatically when Changing Lines Bugs

This is a beta feature in a beta app so it has several things to be ironed out. The feedback for it will be consolidated here.

• Image: when adding a screenshot and then Enter, I get "![]()" instead of the image.. But if I type Space, then the image sticks. Not intuitive.
• If you have type some text and later you want to insert a new line at the end of a sentence, pressing Enter does not work when the cursor is placed at the end of the line. Need to go at the beginning of the next line, press Enter and then the new line is inserted above.
• When the note is longer than the size of the window, if you press Enter to go to the next line, the display of the note goes back to the top of the window. I can still type and if I do, it comes back at the line I am typing, but again, weird.
• Changing lines at bottom of document that is taller than view causes scroll to reset (similar to above bullet point but more general)
• Typing "---" to create divider does not work. But typing "___" works
