The mockup looks fantastic for 4 planes, but check out @rubiohiguey2000’s Central Airways in Idlewild for example, where the holding company alone operates almost 5000 planes.
But technical feasibility aside, those numbers merely point to the real reason why current operations control is so bare-bone: AirlineSim simply isn’t an operational simulation. While such a screen is cool to look at, the player wouldn’t be able to act on most of it. The game is a tactical/strategical simulation, so while a lot of operational aspects are in fact currently missing and should be added over time (see the roadmap), the goal is always to implement them in such a way that one manages them on a tactical/strategic level, but you don’t have to actually do the operations. Otherwise @rubiohiguey2000 would be sitting in front of ops-control 24/7
