It would be nice to give credits to everyone involved in coding and translating in the settings.

A little rolling list of code contributors :-)

@teolemon Got it

[PrajwalM2212]

@teolemon Github api can be used to get list of all code contributors .
Dont know how to get list of translators

@PrajwalM2212 probably easier just to have a file in the app (assets) that can be read into a list, the contributors to the Android project can just append their name onto it in a PR
