1.1. SprintAllows the player to "sprint", increasing their movement speed by a set amount. The amount that the speed is increased by and the sprint button can be changed in the mod's config. There is also an optional setting that makes sprint only available whilst exploring dungeons. The default sprint button is the back button (circle/b/c).
1.2. Auto Advance Text ToggleAllows the player to toggle the auto advance text setting during events similarly to P5R. This comes into effect from the next text box that is displayed. By default this is done by pressing down on the dpad (or s/down arrow on keyboard) during an event. This can be changed in the mod's config.
1.3. Easy Bug CatchingMakes it so the player always gets a perfect catch when catching bugs at the shrine regardless of how you time it.
1.4. Automatic Arcana Bonus On NG+Makes it so the player always gets the social link Arcana bonuses if they have a s.link's max rank item. If you want to see a message indicating this in game it is recommended that you also install the companion Aemulus mod available in the downloads (although the companion mod only gives a visual change, the actual giving of the bonus is done by tinyadditions).
1.5. Visible Rankup ReadyDisplays a symbol next to a social link's rank in the S.Link menu indicating that they're ready to rank up if they are. This applies to every s.link except those that automatically level up during story events and Margaret. The Fox is unique as it will show as ready to rank up once you've completed the current request for it. I didn't give Margaret any custom logic as checking for a specific Persona with skills is more complicated. This addition does not apply to the social link details as of now.
The symbol that is displayed can be chosen between 4 that I thought fit well and the x position of the symbol can also be adjusted. This is done in the mod's configuration and edits take effect in real-time (once you press save) so you can easily find a position and symbol that you like.
