What would you like to see in a modern meeting room display app?

Hi all, I'm a IT admin for small company in the Netherlands. Ever since I went looking for a meeting room display, the options to me seemed pretty limited. A lot of big bloated corporate subscriptions and proprietary hardware was all I could find. So then I decided to build something myself. Now I was wondering, is this something you recognize? and if so, what would you like to see in such a product?

Would love to hear your input! thanks!
