Another irritating issue with Notation Composer is that it hasn't been programmed to recognize sus2 chords. These get bracketed and every time you close, the program tells you "Evaluation of the score shows incongruities with the notation. The file has been saved but it is strongly recommended that you correct these entries in the score using the chord names tool." Well, an Ebsus2 is exactly that. Calling it a ninth will make the warnings stop, but you're inaccurately labeling the chord because a 9th chord contains the 7th, but the sus2 chord doesn't. Being told you're wrong when you're right, and the "chord names tool" is wrong, is highly annoying.
