Mixed casing in address hex text

[Korporal]

Rendered derived addresses seem to contain both uppercase and lowercase hex letters. This makes it hard to search a set of them because a correct hex match will fail a text search simply because a case differs in one of the letters. The public and private keys in the list are fine, they are always generated with lowercase hex letters.

Example:

It is a feature, not a bug. Many wallets and other software around ETH encode a checksum into the casing of the address digits that are letters.
