topics for p5.js editor meeting

[shiffman]

Some of these might duplicate existing issues and ultimately they should be broken out into separate individual issues, but I'm opening this issue just to track a list of things that are coming up in class for us to discuss when we meet to discuss the editor this week.

• erroneous "sketch modified outside the editor" error still happening or fixed?
• should the editor not allow same sketch opened multiple times?
• how to deal with default browser dimensions when using p5.dom?
• how to deal with sketches with multiple JS files (open all in the editor automatically when project opens?)
• what to add to index.html automatically (any new files created CSS or JS or otherwise?)
• how to deal with libraries -- p5.dom, p5.sound, p5.serialport, other contributed libraries
• how to deal with updating p5.js (and other libraries) separately from editor updates
• what warnings to suppress if any?
