[Feature Request] Tags + icons in workflows or an additional "shortcuts" plugin

Hello! 

In previous versions of Ueli it was possible to add additional tags for a workflow and add custom icons. I used this heavily to launch UWP apps on my Windows laptop, e.g., opening Telegram Desktop via typing `tg` or `тг`. It was the number 1 feature why I used Ueli at all. Are there any plans to bring this functionality back?
