I know it's too late to discuss the subject, but it might be useful for others to say that H.A. is the most complete music software available. None, by far, can compare. The flexibility is almost total. There is almost nothing that can't be done. But, it lacks the magnetism to automate the engraving of the layout. It's very handmade. But no software (neither Sibelius, nor Dorico, Musescore, or anyone else you look for, has so many capabilities. It can handle an infinite number of files, both in import and export. The list is endless. Plus, it's surrounded by satellite programs and utilities that complement it beautifully. Pdf to Music, Virtual-Real Singer, MyrSynth, Kooplet, MUSL (Myrweb) etc. It handles the tablatures like nobody else. It lacks a certain functional refinement and the necessary marketing to become better known. But it is really a masterpiece.
