I could definitely use this in my current TFTD LP.
But it is a controversial topic.
First of all, it is useful only in the early game... later you have radar coverage and there's also too much alien activity to track this way. So the player needs a way to turn it off.
Secondly, it does give the player a "free global low-resolution radar", which might go against the design of some mods. Currently, this information is technically available, but it is also insanely inaccessible. You need to check the charts every hour or at least every few hours to use it effectively. And most players are not prepared to do that. Whether that's intentional or not... only Julian Gollop knows. But it's what we have and some mod designers may consider a change from "almost completely inaccessible" to "easy" incompatible with their grand plans. So, a setting for modders to disable this would also be needed.
And no matter, which option you prefer... once it is configurable, all the blame will go to OXC/E devs... players will complain that modders have disabled it for them, and modders will complain that some players have un-disabled it by a sub-mod. Lose-lose situation for the poor devs.
