The most useful part of this software is that it has an easy to use interface which makes any beginner understand very quickly! I have tried other similar softwares but they seem complicated while using them in my daily life i find simuldocs easier with its simple menu structure along side good support from their team when needed ( live chat or ticketing system). Nothing really bad about anything else so far just try out few demos first if you are newbie!! You can easily customize the layout once used properly also there's no restriction regarding word size unlike some older versions like v2 where larger files were not supported at all because memory was limited by 32 bit windows back then :).
