 'Special Pattern' turns out to be especially useful for spotting words groups in part because its setting is independent of the Exclude and Require Position controls. Thus, you can very quickly set and then clear 'Special Pattern' without affecting one's thought train.
 
+'Show Genetic' highlights the highest genetic ranking word in the current showing word list. The highest genetic ranking word is a word from the list that is most in common with the word list in regard to letters. The highest genetic ranking word, or words sometimes, could either rule out the most number of words or rule in the highest number of discovered letters. For example for the word GLIDE, its genetic rank is the sum of all the times its own letters, G, L, I, D, E show up once in each word in the given list plus an adjustment equal to the number of times a letter in the subject word (GLIDE) repeats within the subject word. High genetic ranking words perform well as Wordle plays. It is quickly determined and is often what some people like to figure from the words they think remain. That is why the method is a pywordletool feature. Genetic ranking does not perform as quite as well as groups analysis.

 'Pick A Random' highlights a random word in the current showing word list. There is a point when narrowing down the list of possible words where the higher ranking words are biased against words containing low ranking letters. Any one of the words shown could be the Wordle word. This feature is intended for use when the list has become small where you can surmise the correct word would be a random selection.
 
 'Highlight Group Optimal' highlights the word or words that result in the lowest average group score when that word is used as a guess. The score is the average of the guess's groups sizes. This analysis is performed on the current words 'Showing' or the entire 'Classic', 'Classic+' or 'Large' vocabularies. The group finding process is lengthy and may take extended time to finish. The group optimal guess word is likely to result in remaining smaller word groups, thus increasing chances to find the solution in fewer guesses. Optimal group analysis should be performed on the total selection list that contains multiple letters because the analysis is for selecting the solution versus guessing for letter discovery. A separate window opens to report all the group pattern information during the analysis when the 'Verbose Report' checkbox is checked. Group optimal words identified from guess word sources other than the showing words cannot be highlighted if the word is not in the shown list. Run the process in verbose mode to find out the words. When the candidate guess is of the list there will be some chance the candidate guess is the solution. The solution will be the guess after the candidate guess when otherwise.
