Lots of bug fixes, tweaks, and streamlining in this latest release, including (but not limited to):
“Metroid Buddy” has been added (think desktop buddy, but for the editor).
Graphics Editor has been simplified and support for importing/exporting tile tables has been implemented.
Snapshot quality has been greatly improved in scroll editor mode.
Error traps have been added to prevent smile from crashing on some of the most common errors.
