Json Configuration

A theme object is defined to describe the theme configuration in /ventoy/ventoy.json.
It should be noted that, you don't need to configure every option, you can also configure only some or one of them.

On very few machines Ventoy's menu can't be shown or the cursor moves extremely slow. In this case you can set the default mode to "CLI". However, both "GUI" and "CLI" need a VGA device, if your machine only has serial, you can use `serial` Also you can use `serial_console` if you have both serial and VGA device.
`serial_param`	`STRING`	Optional, will be used only if display_mode is set to `serial` or `serial_console` This parameter is used to set the serial(e.g. port speed), --unit=0 corresponding to COM1, --unit=1 corresponding to COM2 ...... https://www.gnu.org/software/grub/manual/grub/grub.html#serial

Hotkey Tips

Add these following hbox definitions to your new theme.txt to show the hotkey tips. You can also change the position and color.

+ hbox{ 
    left = 30%
    top = 95%
    width = 10%
    height = 25
    + label {text = "@VTOY_HOTKEY_TIP@" color = "blue" align = "left"} 
}

+ hbox{ 
    left = 90%
    top = 5 
    width = 10%
    height = 25
    + label {text = "@VTOY_MEM_DISK@" color = "red" align = "left"} 
}

Ventoy version info

By default there will be a version info string at the lower left corner. For example 1.0.10 UEFI www.ventoy.net
This info is hard coded in the source. You can use ventoy_left/ventoy_top/ventoy_color to change its position and color.
If you want to remove it completely, I encourage you to read the source code, modify it and rebuild Ventoy. I think this is also the essence of open source.
