Some thoughts:

Is it possible to visibly show the black-hole connection, if tested by flight?
My best idea was to include it with hyperplane visibility, which already has a button to show it. Hyper-lane users will see it asap, the other two have to research the built-in HL visibility.
Only other idea might be to have some button like in 'additional map modes' to show it.


For the 3 branches (wormhole, hyper-lane, warp), are there different balances when you are offered to research it? From my view, hyper-lane should have a head-start chance, followed by the wormhole and last but not least warp engine users.

- H-L is often underestimated but could get good push by black-hole travel early.
- Followed by wormhole, which is similar technique, but using point-to-point travel, instead of direct connected black holes, which shows up more like hyper-lane connection.
- Warp drive is something more 'basic' and therefore should get the offer to research black holes on the last position.
