Settings page looks clean. You'll get people wanting more granular controls, but consider if it's worth making the page more complicated. It'd involve checkboxes or many sliders, at least for these:
- Attacks coming in
- Subs passing by
- Mines being drilled
- Specialist hires available
- Other players making hires
- Subs arriving at empty outposts
- Subs getting in a fight
- Subs taking over an outpost
- Subs losing a fight.
Just wanted to list them, I'm gonna want all notifications for the near future anyway.
So far, so good with this test version.
