Added a 'Give feedback' box

I'm a user-centric person and I like to have empathy with the people who use my products 😀. Because of this, I want to allow people to give me feedback 🔄 or to express themselves whenever they want, so I can understand them and their needs, and build a product they like 👨‍💻 and that is useful for everyone 🤗!

To do this, I added a give feedback box in the bottom left corner of the application.
