That is a good point, you can add a space using the space bar in the text bar under the letter pad, but you can ping @KhaozTopsy about it, or drop an issue on the github (Issues · NMSCD/Expedition-Alphabet · GitHub) or hit him up on the discord…however it might be a while before he fixes it, due to some IRL stuff going on right now, he has been away from his computer, and might not get back to if for a few more weeks
