 # Brainstorming
 
-## Questions
+## Requirements
 
-- If a user selects "Paris" and "red", does it mean that they're available but stuck in Paris; or that they're not available but in Paris? (Louis G: first one gives more useful information -- but how to avoid confusion? --)
-
-## Features
-
-- Map `{person,date}` to `emoji representing a location` and a `flexibility state (e.g. green/yellow/red)`
-- One `user` can be shown in several `views` (one `view` can represent a group of friends, colleagues, ... but the `user` only fills the information once)
+- Questions to answer, for each person: Where am I? Can I move? Can I host?
 - Good ergonomics is a must! e.g. selecting a range for multiple edition must be super easy
 
+## Implementation?
+
+- Map {`person`,`date`} to {`emoji representing a location`, `icon for possibility of hosting`, `icon for possibility of travel`}
+- One `user` can be shown in several `views` (one `view` can represent a group of friends, colleagues, ... but the `user` only fills the information once)
