Linking by title is an anti-pattern. Titles change and titles are not unique. Link-rot should always be prevented. Best solution is to use a uuid and hide it from the user.
This is what Quiver does underneath the covers. Every note has an unique id, same as attachments (photos, files, pdfs, etc).
My only problem with Quiver is that it seems that development has stopped, so the chances of adding new bits (like link autocomplete, for example), are thin. Other than that it's a pretty useful tool.
