## ALT/AZ
- Must be able to slew by a given number of degrees
- Must be able to slew at various rates until requested to stop
- Should support slewing at various rates until requested to stop
- Should support configurable min/max positions and limit axis movement accordingly
- Should save home and current position to EEPROM

## Focuser
- Must be able to slew at various rates until requested to stop
- Must support slewing to a specific target position
- Must be able to set motor position

## General
- RA and DEC operations must be independent, but can overlap
- Stepper operations must be async
- Would be nice to get an event when the stepper stops
- Serial message processing mst be sequential, but async and in the background
- Serial message processing must be sequential, but async and in the background
- Serial connection default speed should be 115200
- Must be able to convert from RA/DEC coordinates to stepper target positions (must use solution with longest safe time)
- Meade Protocol support for OAT/OAM/OAE
- Should be able to return safe time left
- Should be able to return time to meridian for current position

## Menu/Display
- Support Info-only displays to show mount status
- Support LCD?
- Input devices? Buttons, joysticks, touch?
- List of operations possible from interactive display devices
- Support LCD screens (small, large, color, mono), but maybe start with common/standardized size
- Should support input devices like Buttons, Joysticks, Dial with press point, Touch screen
- Need to come up with a list of operations possible from interactive display devices
- Move any axes in any directions at various speeds
- Start/stop tracking
- Find home position
- Go to Home position
- Enter target coordinates and slew there

## Sensors
- Support for RA and DEC end switches
- Support for RA/DEC homing switches
- Temperature sensor?

## Improvements from 1.0
- Support meridian flip? (how is this done when using camera in another app?)
- Support meridian flip. This should already be supported in apps like NINA, if the sync to coordinate takes the longest safe time.
- Dew heater support?
