Firstly, I've been trying out new fonts in order to support new characters and languages. Here is an example of a google font that supports Japanese characters. 

Since the fonts are much too big to reasonably store on the flash they must be stored on the SD card. The flash still carries a basic antialiased latin alphabet font which is used if the font file cannot be found on the SD card or there is no SD card present.  Also, now if there is no SD card present on boot the homescreen will display a "No SD card" message momentarily every time you enter the homescreen.

Ive also been experimenting with wireless file transfer with the excellent code from 
G6EJD (https://github.com/G6EJD/ESP32-ESP8266-File-Download-Upload-Delete-Stream-and-Directory/tree/master). My test reveals that this system can transfer files at a speed of about 0.5 megabits per second. This is a very low speed for file transfers especially when you get into bigger music files. This system as it is would take an hour to send across 60 4 minute long compressed music files. I think i'm starting push the speeds of 1-bit SPI mode. An obvious solution to this is to go into 4-bit mode but I am not really comfortable on the software side. Even if I was im starting to dislike the wireless approach, having an sd card reader built into the board costs about a dollar in parts and means I can sidestep all wireless and 4-bit business. Simple usb mass storage drag and drop is really what I want, so I might as well built what I actually want instead of trying to make the cleanest most perfect solution. Also the wireless transfer is pretty inconvenient even if it was was faster and it only works when you have access to wifi.

That makes the plan for the V3 as follows:

-Add SD card reader chip with USB switch to switch between programming and SD card

-When using card reader set the SPI pins as high impedance on ESP32

-No wireless file transfer

Id love to hear some opinions
