I have about 250 logins in my vault and probably 85% of the usernames are my personal email and 95% come from a list of 4 other usernames. Most logins are created with the browser extension but I create them in 1Password when I need to sign up for a native app on either iOS or the PC. I'd love to have a list of my top usernames sorted by frequency in my vault right underneath the text field for "Enter your username or email address". Almost every time I'd just tap the first one and move on to generating a password. This might be nice on the desktop platforms but I'd really like it on mobile where typing is harder; especially with my third party keyboard disabled (by default).
