Link Asset Fallback Title

[christianruhstaller]

When you output the property text on an asset type and you do not have a custom text specified Linkit will output the filename of the asset.

In the Craft 2 version of the plugin the title of the asset was returned.
In my opinion it is better to return here the title also and not the filename because it should be a descriptive text.

Is there any reason that this behavior was changed?
