Roadmap and wishlist

Interval/timer

Once we have moved to a card-based display for per-expression "output", I think it would be interesting to add the interval function from cells. The implementation I have in mind is one where the expression thus wrapped would run repeatedly, each time updating the component view that it produces.

We would want to make it such that:

• we never have more than one interval running for any code block
• re-eval'ing the code would (on success) switch to the new function, on failure kill the interval and switch to an error card
• the card for an active block would have a "stop sign"-ish icon to stop the interval
• some dynamic variables are bound in the interval fn, like *mouse-x* and *mouse-y* (adjusted so the card's top/left is 0/0)

It would also be nice if each interval'd expression kept a counter from when it started running, incing it at each callback. Maybe *tick*? This would make for a nicer Processing-like experience for animations.

Card sharing

A publishing mechanism not just for the source code of a buffer (i.e. similar to our current gists), but rather for the "card view" of a project, which is then like a micro-webapp.

Copy/paste of shapes

It would be nice if selecting and copying a shape (and similarly with other special output) from the output pane copied the source code to produce it.
