Here’s a problem with both the Lite and the Full version. If I select all the text in the Bundle ID field and then hit the delete and then command-z nothing happens. If I do the same thing with the fields below, “Copyright”,“Version”, and “Build” hitting command-Z does do an undo.
Unlike the other two, the Bundle ID field isn’t a simple text field, in that what you type is filtered — you can’t enter characters that are not allowed in IDs. Once you start filtering like that, the built-in undo of text fields unfortunately breaks down.
In other words this is not a bug it is now a feature
