Is your feature request related to a problem? Please describe.
Whilst the freeflight mode provides exceptional opportunities to discover the map from a browser, it doesn't respect collisions, eg you can fly through stuff.
This leads to users being able to find hidden bases, explore caves and mine systems they've never been to etc.

Describe the solution you'd like
An option to toggle collisions on a per-map-basis, so that users cannot fly through blocks/doors etc.

This is sadly not feasible.
