Maybe it is my imagination, but saving with code-signing on seems significantly faster in SD7. I used to leave it off until I was ready to distribute a script. Now, it’s not painful at all to leave it on. Maybe an extra second.
All that being said, the new resources features are great as well, including the ability to only code-sign when exporting a script. It is great having that and the library bundling feature, plus more, included in the resource pane. I’m sure I will be taking advantage of the extension and UTI filters as well. Great features!
