Dear @nitz,
In order to meet the requirements for aZ0- type of characters in passwords, but at the same time be able to easily remember such a password, I want to use the random whole WORD mode. At present, KeePassDiceware 2.0 has the whole WORDS mode, but its output is often unsatisfactory because it lacks lowercase as follows

SEVEN-5-HONEST-WHISPER

Please, replace WORDS with WORD, or make it a separate word casing mode to get

seven-5-HONEST-whisper
