Hello particle community, I just got my Electron the other day and obviously wanted to flash the unit via USB 
but to my surprise I can’t do it via the Web IDE an obviously I wasn’t going to use 22kb of my precious wireless data 
. so I used the terminal option connecting over USB . And now that the Electron is out of pre orders and people might be in my same situation as me and maybe they are not as advance as me (not really ) 
, but seriously not all beginners know how to use Terminal (mac) and depending on what they do they can delete files accidentally
Side note: raspberry pi is the best why to learn how to use the command line
Anyways this is my recommendation to particle. I have an X-carve this is a cheap and simple CNC and they have a very similar way to interact with the device. it uses a Web app to send the G-code to an Arduino via the USB on the computer.
They are able to comunicate with the unit with a background app that you have to download and when you use the web app Easel it knows that unit is connected.
hope this can be implemented in the future.
