Few useful additions for your library, which will be great to have:

1. RPickMedia.kt: Add ability to pick File (not photo, not video) with optional to filter by mime type
2. RPickMedia.kt: Add optional properties to pick video from camera(during of video, size of video, etc)
3. RIntent.kt: Add ability to send sms with body text
4. RStatusBar.kt: Add ability to change status bar theme(dark or light) -

5. RActivity.kt (new): add ability to change activity with ext, optional request code to start for result, optional clear flag(to clear backstack), etc.
   ... Will be populate issue with new ideas. Thanks for your library, very helpfully!
