Kryx, thank you for the clarification on Concentration. So this is what I mean: - Drag Bless from SRD into an empty spell - Duration populates with "up to 1 min" and the "concentration" button next to it is highlighted. Visually, this works. It's "part of duration" in the sheet in a way, though it's not actually in the duration field, but next to it. During output, "up to 1 min" is output, but "Concentration, " is not there, and now I understand why. For output then, I think you have a choice: a) Output duration and prepend "Concentration, " if the concentration check-button is set or b) During import, leave "Concentration, " as part of the duration text field. Personally, I like a) better. It allows for filtering, and is visually neater than having "Concentration, " in the duration field, because it draws the eye to the "Concentration" button. That's an important piece of information to have, given how concentration works.
