This suggestion is for after Advanced Radar is implemented.
After researching Advanced Radar, selecting an researched UFO should show not only its type and speed, but also its mission (recognition, retaliation, supply, alien base, terror, etc) like on old X-COM. This feature would add some tatical options for the player (like deciding intercepting priority for example).
This way, Advanced radar wouldn't just be a radar with larger range (this would be pretty disapointing).
