Considering some UI changes

[eduvik]

I'm starting to imagine how the UI could provide a better workflow. I'm thinking of:

• putting the file panes as a side-bar on the left
• having a 'new project' button that creates a new project folder, which contains a settings file for that project, and create boot.py and main.py files (with some boilerplate starting comments/code)
• sync buttons (in either direction) that will copy all files from the project folder to the device (or vice versa)
• a 'run' button that will upload and run the current file

Any suggestions or comments would be appreciated
