suggested improvement/LEARN - Recording Sound with the micro:bit v2

I am a newbie using the LEARN pages to learn how to use Microblocks. I noticed that it took quite a bit of searching around to find some of the blocks used in the example code for “Recording Sound witn the micro:bit v2”.

Could you please consider adding something like the following instruction to the page, perhaps just after the Introduction paragraph:

To do this project, you will need to turn on Advanced Blocks by selecting "show advanced blocks" from the MicroBlocks menu in the menu bar. This will let you use the initialize local var to xxx, the new list length and the wait xxx microsecs blocks. You will also need to select the Microphone item from the "Sensing" group of the "Libraries+" menu

Thanks in advance.

Alex
