It would be nice if the browser extension UI detected when a user had caps lock enabled while typing in their master password and notified them in the UI. Here’s an example of a browser extension detecting this.
This would prevent the scenario of a user typing their master password in over and over (assuming they’ve typo’d it) until finally clicking the “eye” icon and seeing that the case of the password they’re typing in has been reversed due to caps lock.
I often have this problem (I am a fast typer and sometimes Caps-Lock is turned on).
Such a hint would prevent that I have to type the master password several times.
An easy to implement feature that increases the usability a lot!
