Just put in where u at and where u goin.
Oh there's a bloody third party tool for this?
Mystery solved, we know why it isn't in game yet.
Every single time someone goes to the trouble of doing FDev's work for them like this, they take it as a cue to say "well now we don't have to do it" and resume looking for more colourable things to slice off the game and sell back to us piecemeal on the store.
Y'all remember that time the third party devs got sick of FDev's crap and shut down all their services for a few days? Best thing that ever happened to this game, really lit a fire under their backsides, and the only thing I didn't like about the whole affair was that they brought them back up afterward.
Never forget they are a profit driven business and will take advantage of all the generosity and free labour time you're willing to give them for no reason other than you're sick of waiting for them to do it themselves.
Add that not everyone is willing to go through the hassle of installing half a dozen of these extra tools made by who knows and drawing extra resources (I'm certainly not) just to use features that should be in the game as standard.
Bring the whole thing crashing down, the uproar alone will force FDev's hand. If you're good at something, never do it for free, they're laughing at you all the way to the bank.
A little hyperbolic for effect but you know this all to be true if you remember the event I'm talking about. People badly want these features and the only reason FDev won't provide them is because someone else did it for them. Mods and enhancements are one thing every game gets from its community for but the devs to shamelessly use them like this says to me in this case they should stop for their own good and the good of the game long term.
