Block Enter is designed to enhance user experience on chat platforms by preventing unintended message submissions. Often, pressing the Enter key can lead to sending incomplete thoughts or accidental messages. This extension specifically addresses that issue by disabling the standard Enter key function for submitting messages. Instead, it allows users to easily send messages using the combination of Ctrl or Command + Enter. This feature is particularly beneficial for those who like to craft their messages carefully or work in environments where message clarity is crucial.
