• It's possible to override any image in web application without overriding default ones
• It's possible to override any CSS in web application without overriding default ones
• It's possible to override any template without overriding default ones
• It's possible to override any class
• It's possible to override any module, or just a single url
• It's possible to override translations
• If you are not sure which template is used enable debug output
• If you change templates and nothing changes disable cache
• You can write your own extensions
• We are using bootstrap 4 CSS framework.

Each time you are modifying original files you are losing upgrade capabilities. Live Helper Chat is very flexible and allows change almost everything without changing kernel.
