The ability to switch between screens quickly, especially when using mobile devices! I also love that it's web friendly - so there is no need for additional client software or hardware other than what you already have available in your organization (PCs/laptops). Having different types within one screen can be problematic sometimes as well with how they appear visually from each side but we've been able solve them by adding extra space around elements which are too close together at times :) Great product overall though if used properly will save quite some money over traditional methods like digital signage networks etc.. Time savings alone make this an excellent investment decision since our old network system was very outdated compared others online systems out now today such has MeviS!!
