With the default font in Locknote, there is no visual difference between the lower-case "l" and the number "1". This is also the case for the upper-case "O" and the number "0". When reviewing the contents of an older Locknote, the only way to discern exactly which characters are present is to copy the text and paste it into a different application. This is important for me as I primarily use Locknote to store IDs and passwords.
Please change the default font to one that has visually different characters for every letter and number.
