Title: Strings

More string processing power! Substrings, levenshtein distance, string comparison, whitespace trim, case conversion, and regex replace. (The addition of the regex replace block doesn't preclude the possibility of an entire regex category in the future to simplify the actual *building* of regular expressions, since blocks from that category could simply be dropped into the regex replace block.)
