In Version 2.5b (1126) the “Decompose” and “Unlock component” context menu seem to have disappeared when I started Glyphs today. The first does not matter so much, since it is available under the “Glyph” menu, but I just locked a component and now there is no way to unlock it?!
I tried with a fresh font, as well as with no plugins, however the context menus remain missing.
