Night mode feature on electronjs

Electronjs is a platform helping people create desktop apps easily and this is making the platform very useful.
The platform has very huge brightness which makes it very good to use day time as users don't need much phone brightness to use it during the day. But this can't be so during the night, because becomes too much and not advisable for users using phone with high brightness.
Example of images of the platform

Suggestion is for the addition of the night mode feature on first page so users won't be having brightness issue with the platform when using it. So the platform should be having something similar to this.

With these users won't need sun shade to browse throuh the platform at night and no brightness issue.
