1.6.0

• New: device groups — organise screens by location or purpose (Lobby, Cafeteria, Menu Boards) and push content or a whole project to every screen in a group at once
• A screen can belong to several groups, each with its own colour; the Devices page shows group tags on every TV and lets you filter by group or show only ungrouped screens
• Group pushes tell you exactly what happened — how many screens received the content and how many were skipped because they were offline
• Fixed: a TV that reconnected could silently drop out of its groups
• Fixed: renaming a device no longer risks clearing its other details
