Being able to sort search results by a yaml key and/or date would remove the need for file name date prefixes. File name date prefixes OR key/value pairs are required to maintain file creation date persistence in the event system creation dates are lost in files.
Also date prefixes are ugly in search results, graph view, links with aliases, dataview queries etc. It takes a lot of effort to make them pretty.
Implement sort search results by custom yaml key/value pair. Specifically date.
Use date prefixes.
