1. That would be a possibility for more random scenes to happen, if time allows it that would be a possible thing to add (Toni has something similar when asking for the tool at the alley)
2. More outfits with scenes are planned but not as a "outfit selection" for her to wear during the day. This would create a lot of variation on cgs and sprites to be done. But more outfits are planned to be implemented and in thoughts to have scenes linked to them, similar to the teacher, gold bikini, and black bikini outfits.
3. There won't be fully public scenes, and there won't be NTR scenes of any kind. Anything that Anna does will be dependent on user input, so no random groping or such will happen.
As for the questions:
1. Already answered (yes)
2. Yes, the focus is to increase content for the characters that are already in game, with a couple of new additions. Kate might receive something, but as for Sam, she is considered "completed" (she is the side character with the greatest number of scenes) but might receive 1-2 more scenes. 1.9 will have the continuation of Alice and Norah for example.
3. It's a possibility.
