Hi @claritza42, it is true often the developers are in background and we do not know them, but @alejos7ven is one of the well known and one of the developer who is always easy to reach and communicate. I like his attitude that if there is any question and he can create something to help with he does it with pleasure. I also used often his tool for "booming" check and found it very helpful. Wishing you success with the challenge!
