Will be implemented random failures (setting in scenario file - just like in "Project Mercury")?
At least for the Igla docking system, given it had a very low reliability during the first Soyuz7K-T missions ; the cosmonauts had often to try to achieve docking approach manually.
The main engine failed once on a Salyut missions, and cosmonauts used the backup engine to deorbit. Also, parachute failures could be interesting, considering there is a reserve chute. But we'll see that sort of things when the nominally-working addon will be finished
Some changes on the MWS as suggested Urumpwe :
Now there is a small "Alert" or "Avaria" indicator on the HUD, and you press a key to display the full panel and see what's going on. Here, the three yellow alerts simply indicate that you are passing in range of communication station (so you are receiving telemetry, and it is a good time to plan manoeuvers).
