No backspace

Good at conversion, but no backspace. It is easy when entering a hexadecimal number to find you need to backspace out an errant keystroke. Here you must clear and re-enter. There is a < mark on the keyboard, but it doesn't do anything. It would also help readability if each base was delimited by its typical separators such as a space every four binary characters and a space every two characters for HEX and a coma every three for decimal
