They said in the Q&A after yesterday's panel that they want this & that it will be happening along with a bookmarking system but that it might not be done in time for Chapter 4. It also sounded as if the current POIs on planets will all be detectable using the new probes which does solve a lot of the problems regarding particularly new commanders accessing planetary content.

It's good that they mentioned that they want it.
What seems odd to me is why they can't include this in the Q4 update.
I added it into Captain's Log in about a week of on and off coding and UI design and all the code glue that entails - I had to learn about the Haversine Formula and I had to research into how to also calculate a 'direct' distance to a target location from an altitiude (CL2 does both depending on if your vehicle is on the ground or if flying your ship) and translate that into Python code - and I am just one guy.
Now. I'm not saying this is a trivial addition, as I don't know ED's code base and I don't know what goes on day to day in the ED offices or how dev time is allocated or even if they have enough devs there to do all the things that Frontier tries to get into the dev schedule for a particular update. On the other hand, to me it doesn't seem like it's such a monumental task to add something like what Captain's Log 2 now has, to the game, that it would take so much dev time away from all the other Q4 goodies - considering the outright benefits of adding such a thing to ED would give to all its players.
