I needed a digital menu system that could scale easily and wasn't a hassle to run and Nexsigns is exactly this.
None that I can think of at this moment. Everything has worked as expected.
As the main user of my organization, the most important feature isn't a feature per se, but more their stellar support. they are always there and ready to help when there is an issue.
I love the software and am waiting to see the next round of updates.
