3.- Error messages: at least like in the old compiler.
I would like to see a different way of editing code: any modifications in a code pane are assumed to be unsaved changes to the source code. This means that things like "Print it" and error messages should go to a separate text pane on the UI somewhere - maybe a pop-up at the location of the error, or in a status bar, or maybe a separate list of errors/warnings like other IDEs do???
I haven't looked at the code for reporting error messages, but I'm assuming (and hoping) that the compiler just reports an error message and a character index, and the "presentation layer" does the notification?
