Completely rewritten with a new approach. Instead of adding missing features to the founder lens, this now links the settler lens to the Founder unit and completely ignores the founder lens. When selecting the Founder, you get the settler lens, with all the features the settler has as well. The previous version of the mod still missed the tooltips from the settlement recommendation and the flooding/eruption warnings. No longer!
Special thanks to
@wltk for their Discovery Lens, on which I based the new coding.
