Here are the classes, structs, unions and interfaces with brief descriptions:

NPurePursuit
CPath
Cspline
Chermite_point
Nscreen
CButtonWidget	Widget that does something when you tap it. The function is only called once when you first tap it
CFunctionPage	Simple page that stores no internal data. the draw and update functions use only global data rather than storing anything
COdometryPage	Page that shows odometry position and rotation and a map (if an sd card with the file is on)
CPage	Page describes one part of the screen slideshow
CPIDPage	PIDPage provides a way to tune a pid controller on the screen
CScreenData	Holds the data that will be passed to the screen thread you probably shouldnt have to use it
CSliderWidget	Widget that updates a double value. Updates by reference so watch out for race conditions cuz the screen stuff lives on another thread
CStatsPage	Draws motor stats and battery stats to the screen
NVDP
CAbstractDevice
CMotorDataRecord
CNumber
COdometryControlRecord
COdometryDataRecord
CPacketHeader
CPacketWriter
CPart
CPIDControlRecord
CPIDDataRecord
CRecord
CRegistryListener
CString
CTestRecord
CTimestampedRecord
CUpcastNumbersVisitor
CVisitor
CAsync	Async runs a command asynchronously will simply let it go and never look back THIS HAS A VERY NICHE USE CASE. THINK ABOUT IF YOU REALLY NEED IT
CAutoChooser
Centry_t
CBasicSolenoidSet
CBasicSpinCommand
CBasicStopCommand
CBranch	Branch chooses from multiple options at runtime. the function decider returns an index into the choices vector If you wish to make no choice and skip this section, return NO_CHOICE; any choice that is out of bounds set to NO_CHOICE
CCommandController
CCondition
CCRC32	A class for calculating the CRC32 checksum from arbitrary data
CCustomEncoder
CDelayCommand
CDriveForwardCommand
CDriveStopCommand
CDriveToPointCommand
CExponentialMovingAverage
CFeedback
CFeedForward
Cff_config_t
CFilter
CFlywheel
CFlywheelStopCommand
CFlywheelStopMotorsCommand
CFlywheelStopNonTasksCommand
CFunctionCommand
CFunctionCondition	FunctionCondition is a quick and dirty Condition to wrap some expression that should be evaluated at runtime
CGenericAuto
CIfTimePassed	IfTimePassed tests based on time since the command controller was constructed. Returns true if elapsed time > time_s
CInOrder	InOrder runs its commands sequentially then continues. How to handle timeout in this case. Automatically set it to sum of commands timouts?
CInterpolatingMap
CKalmanFilter
CLift
Clift_cfg_t
CLinearPlantInversionFeedforward
CLinearQuadraticRegulator
CLinearSystem
CLogger	Class to simplify writing to files
CMaybeMessage	State Machine :)))))) A fun fun way of controlling stateful subsystems - used in the 2023-2024 Over Under game for our overly complex intake-cata subsystem (see there for an example) The statemachine runs in a background thread and a user thread can interact with it through current_state and send_message
CMecanumDrive
Cmecanumdrive_config_t
CMotionController
Cm_profile_cfg_t
CMovingAverage
COdometry3Wheel
Codometry3wheel_cfg_t
COdometryBase
COdometrySerial
COdometryTank
COdomSetPosition
CParallel	Parallel runs multiple commands in parallel and waits for all to finish before continuing. if none finish before this command's timeout, it will call on_timeout on all children continue
CPID
Cpid_config_t
CPose2d
CPurePursuitCommand
CRect
CResponsePacketVisitor
Crobot_specs_t
CRotation2d
CScaledSphericalSimplexSigmaPoints
CSerializer	Serializes Arbitrary data to a file on the SD Card
CSpinRPMCommand
CState
CTakeBackHalf	A velocity controller
CTankDrive
Ctracking_wheel_cfg_t
CTransform2d
CTranslation2d
CTrapezoidProfile
CTurnDegreesCommand
CTurnToHeadingCommand
CTwist2d
CUnscentedKalmanFilter
CWaitUntilCondition	Waits until the condition is true
CWaitUntilUpToSpeedCommand
