Use H1 or YAML property "title" instead of or in addition to filename as display name

Please, consider complementary simple request that will make this one much more useful in the future:

Start treating YAML "title" field as one of aliases

Use cases: Use existing databases with specified titles effectively, eliminate the need to [duplicate title into aliases field and then maintain them in sync]. This feature would be simple initial step towards support for vaults with UID based filenames (Zettelkasten). Proposed solution: Add option to treat YAML “title” field as one of aliases. i.e. when the option is toggled ON in settings (or in some config file) for given vault, then return title as match in auto-completion during linking …

• By putting title directly in “title” field instead of “aliases” field, we will have it ready when this request is implemented.
• When we will see titles daily, we will want them to match in quick switcher and in link suggestions.
• “Title” field is well defined, manageable by plugins so in case of need we would be able ourselves to fill missing titles by data extracted from markdown by some plugin to satisfy diverse opinions for how exactly this request should behave (what data to show instead of filename)
