Description of the new feature / enhancement

I would like to see a new feature in PowerToys, which, when user types colon ( : ) with no following space, will show small tooltip with emoji suggestions on top.
This feature will be similar to Rocket app for MacOS. Demonstration from their website:

Additional suggestions for the feature:

• Parse emoji codes no matter the input language (transliterate letters in non-enlish locales to show proper emoji suggestions as if the text was inputted in English)
• Configurable trigger symbol ( :::\ )
• Configurable codes for specific emojis
• Excluded apps list

Scenario when this would be used?

This will be useful to get ability to quickly insert emojis in apps which don't support keyboard-based emojis.
