For me the button associated with path selection should be always visible not only in edit mode.
Of course, this can be changed. But TheIDE's configuration dialogs usually hide the path selector until the array is in edit mode.
Wouldn't it be inconsistent with the other dialogs?

There is a bug at least on my machine (Latest neon). When the list is opened you can click on it and the empty entries will be created. We shouldn't create new entry where there is no content associated with it.
