As a creator who works with AO / config notecards that use ":" as a common part of their code, the current Emoji Popup menu behavior is extremely inconvenient, distracting, and even annoying as it makes a sound with every keystroke of a new letter after the trigger.
An option to toggle the popup menu off for Notecards and even Chat would be greatly appreciated. There is already a request to have the trigger configurable - but many of us would just plainly prefer to turn off the popup menu entirely.
