Anytime I enter a typo, SKP learns this as a new word, and it becomes a suggested prediction too easily.
Suggestion: If I use backspace to edit into a word, and that word was one of the most recent learned words, UNLEARN that word. Remove it from the learned words list.
Suggestion: Don’t learn words which have digits in them. Those can still be set in custom keyword expansions. Otherwise are probably not something to be memorized. It can lead to replacing with the wrong number: entering “bug3725” is replaced with bug3722 too easily. The learned dictionary and prediction bar gets loaded with too many rare words with digits.
