The "Watched By" feature has a field titled "Note:"
For my purposes I found the field very useful until I learned the following.
I can enter a relevant note then click OK and it seems to work; however, the next time I open "Watched By" for that same movie, THE NOTE IS MISSING.
What is the purpose of entering data into a field if you cannot review the field content later?
How may I view the contents of the Note field after I close the "Watched By" window?
