I put some effort into improving the printing friendliness in sage-3.0. Especially the text in input cells should never overrun margins, etc. The output could. Click on the print button for the printer friendly version of a page. > (2) One student did this, as did I: accidentally clicked on a bookmark > while working, then clicked back to the page to see work was lost. It wasn't lost. They should have pressed refresh. This would have updated the page to the current state. The server always has the current state even without autosave. Saving only makes a snapshot that's in the browsable revision log. There are two ideas about how to fix the browse away and press back button issue: (1) make it so any time any browser window is looking at a worksheet, if it gets out of sync with the server's view of that worksheet a refresh is forced. This is useful also if multiple browsers are viewing the same page. (2) somehow make it hard to navigate away from a worksheet (e.g., via an alert). I've tried (2) but didn't like it. Implementing (1) is nontrivial and opens a can of worms, but I would still like it to happen. > How do you change the autosave interval to be something shorter?
