There's a step-by-step tutorial (accessible via the options screen). Personally I think it's quite cool and It'd be nice to make it more obvious for new users (and maybe to encourage people to contribute more tutorials).
Some kind of 'error log' accessible from the Options screen would be cool - so if flashing failed or a module couldn't be found, more information could be displayed somewhere.
The graphical code editor always seems to place the 'example' code slightly offscreen, and I could never figure out how to fix it :) It'd also be great if it could remember what the last used code was (like happens on the text editor)
The console on the left actually has a thin (2px?) border around it that is grey when it is not focussed and black when it is. Making focus more obvious should be a relatively simple job of modifying that CSS.
I hate the orange colour scheme, and I'm sure everyone else does too. Please don't feel bad about completely changing it :)
On the Espruino website there's the search box (it's pretty easy to see how it works - it's just JSON). I end up using it all the time to find information on functions/devices/modules/etc so it might be cool to have some kind of shortcut that allows you to use it to quicky find information.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Great! Just thought I'd add:
