     - Non `y=` functions.
 3. Smart display of graph
     - Display of intersections between functions
+    - Add docs about roots and extrema
 4. Fix integral line
 5. re-add euler's number (well it works if you use capital e like `E^x`)
 6. allow constants in min/max integral input (like pi or euler's number)
 7. sliding values for functions (like a user-interactable slider that adjusts a variable in the function, like desmos)
 8. Keybinds
 9. nth derivative support (again)
