Making easier to see what is available and what isn't

It seems that XY homing on a new print doesn't work after this function runs. The nozzle stays in the center of the bed, and fluidd reports a coordinate out of range error. A hard reboot clears it.

Here's my start g-code in Orca:

M220 S100 ;Reset Feedrate
M221 S100 ;Reset Flowrate

M140 S[bed_temperature_initial_layer_single] ;Set bed temp
M104 S140 ; Preheat nozzle

BED_MESH_PROFILE LOAD=default 

G28 X Y ;Home XY axes
G28 Z ;Home Z axis & load bed mesh

M104 S[nozzle_temperature_initial_layer] ;Set nozzle temp
G92 E0 ;Reset Extruder
G1 X-1.0 Y20 Z0.3 F5000.0 ;Move to start position
M190 S[bed_temperature_initial_layer_single] ;Wait for bed temp to stabilize
M109 S[nozzle_temperature_initial_layer] ;Wait for nozzle temp to stabilize
G1 Z0.2 ;Lower nozzle to printing height
G1 Y145.0 F1500.0 E15 ;Draw the first line
G1 X-0.7 F5000.0 ;Move to side a little
G1 Y30 F1500.0 E15 ;Draw the second line
G92 E0 ;Reset Extruder

• [ IMPORTANT: DISPLAY UART IS LOCATED ON PIN PA3,2 (USART 2) and not on USART 3 PB11/10 as documented by others ]
• [Document the icon retrieval process as a separate .md page]
• [Add github pages for documentation export as page]

Make a webpage with the installation, reverse engineering and code docs

• Create a run file with default values for COM, baud and other from a configuration file
• Make it accessible via CLI command
• Package as Pypi

Values need to be cleared or a background need to be set

As README is exported as a webpage, the checkmark emojis need to be replaced by the html entity code "✓" and "✗" instead to be correctly rendered:

The screen communication protocol can be extended for response messages from the display unit to the klipper host.
Extend rotary button methods already available from klippy so that the screen rotary button and its commands (left, right, click) are registered and translated as a UART message sent to the host. The protocol will be as follow:

Each of the 3 inputs (left, right, click) will be a corresponding bit on the command, following the logic:
(BTN_CLICK<<2) | (BTN_RIGHT << 1) | (BTN_LEFT)

Note: To be done after screen is complete.

Add menu items for every subitem under the "prepare menu"

Change the respective menu icons for other languages using its respective library IDs:

• [ Add language submenu under "Prepare" menu]
• [Change icon set when another language is selected]

A serial bridge was already proposed and implemented by @
E4ST2W3ST, but it need to be adapted for the ender 3 v3 se with the following changes:

• [Change port forwarding to match E3V3 serial port (from USART1 to USART 2 (RX on PA3, TX on PA2) ]
• [ Create virtual rotary button that generates UART messages from rotary button state]
• [Port existing Display, Screen interface and printer interface to klippy]
• [Packaging and release]

I was attempting a cold pull by setting the nozzle temp on idle, but the temp just resets back to 0, so I had to do it from fluidd.

This serves both as a question and an enhancement request,
What menus/features are currently supported? An what is still pending?

Also, thank you for you amazing work!

At the moment, the whole action menu is updated every cycle without necessity. This makes the screen flickers and consumes time that will be important when porting this to klipper.

• [ Remove method to update status bar on every menu, move it to a timer-based update]
• [Store last values and compare them before updating the screen, drawing only values that actually change]
