[FEATURE REQUEST]: Icon customizer

### I have searched through the issues and didn't find my problem.

- [X] Confirm

### Description

- New feature that users can customize icons
- Insert outline to the icon
- Turn the icon into monotone icon
- etc...

### Context

When I use icons like Apple or Kafka on the black background, I need to create something like white outline to show the icon.
It started from this situation, and I just have imagined about icon customizer. For example, another free icon website 'Flaticon' is providing some functions to adjust colors, flip or rotate icons, or add background with certain shapes to the icon. I guess it would be so useful to users.
