For me at least, not wasting time using the FSS to help determine if I want to take the time to explore a system further. Personally, I don't really consider using either the FSS or the ADS to be "exploration," beyond the mechanics of game-play progression.So what can you do with the ADS that you can't do with the FSS, except get an instant system map?
For me, I'd say I'd rather just have nondescript world targeting info on the ship nav. panel and HUD after the honk than have a system map at all, and likewise for the DSS for that matter. I'd rather explore systems in first-person game-play flying my ship around.
Re-implementing optional, expandable functionality similar to the ADS in this regard would be a compromise for me. For the added functionality and to not undermine the FSS, I think it's fair that it would need to use a module slot as it did previously whereas the FSS dose not use one, and to be better incorporated with the FSS. Assuming both the FSS and ADS equivalent are used together, have the targets show up on the FSS view after the honk, but without providing the detailed world information unless either using the FSS as it is now to dial and zoom into worlds or, as previously with the ADS and old DSS, fly out to worlds within range.
That being said, and sorry to say, OP, I don't think betas are generally considered an appropriate place for changing around game features, just testing the functionality of existing and added features that are already determined to be changed by that time.
