Saving ufo as Glyphs file?

So I open a ufo, work on it (adding masters etc), and then try to save as a Glyphs file, except there is no Save As. And I can’t save it as a ufo either without exporting the masters separately. Am I doing something wrong? How can I Save As a Glyphs file? Once I open ufos, I can only work with them as ufos?

sorry, this issue concerns 1.4.3/1.4.4

This is OS X’s way of saving things, called ‘Versions’. What you want to do is called File > Duplicate . Read this article:

If you prefer the old wording and saving mechanism, try Glyphs > Preferences > User Settings > Pre-Lion saving behavior
