Cura 4.8.0

[Danthelad 0]

I updated/installed my version of Cura 4.8.0 on the 1st December 2020 and have found a few things that I have noticed;

Whilst going through a YouTube video, explaining about using the colour mixing facility on a recently purchased Geetech A20M, it states that you should be able to add more extruders in the machine settings options. However, on the version I am using it is set at a fixed number of 2 only. Has this facility been omitted/scrapped? Is there a more current version of Cura?

Also, is there a written step by step explanation of how to use the colour mixing plug in "ColorMix 2-1 V1.2.1" It seems very obscure how to use it from the information given within the plug in itself?

Thanks In Advance
