What this addon does is to remove all duplicated letters or symbols in a string. Simple, clean, user friendly and valuable addon in my opinion even if you do not use it as a sigilizator but as a remover of duplicates. Highly recommend it.
Really cool and useful tool !!! Just try it. Very easy to use and saves a lot of time. Really helpful - I'm quite happy about it and could sincerely recommend it to anyone interested in sigil building:))
