Some other hex editors I use (e.g. the one included with Visual Studio Code) allow users to copy the selected range as Base64 string, which has the advantage of being more compact.
Plus, decoding Base64 strings is a one-liner in many programming and scripting languages, while parsing space-delimited hex strings usually requires some custom boilerplate code.
