Hey! Thanks for taking your time to contribute to this repository. The app looks good in the full screen, however there's some corrections I would like to suggest.
Resizing of 'send' button and input field is required as it looks a bit unusual in the full screen
The application needs to be responsive for the mobile devices as well.
The vertical height must be 100%.
Took a swing at this one after finding this project on a list of projects that need help. Feel free to request changes or outright reject the request!
