Avoid duplicate identifiers when exporting Denote notes
When exporting Denote notes to, for example, an HTML or PDF file, there is a high probability that the same file name is used with a new extension. This is problematic because it creates files with duplicate identifiers. The ‘20230515T085612--example__keyword.org’ produces a ‘20230515T085612--example__keyword.pdf’. Any link to the ‘20230515T085612’ will thus break: it does not honor Denote’s expectation of finding unique identifiers. This is not the fault of Denote: exporting is done by the user without Denote’s involvement.
Org Mode and Markdown use different approaches to exporting files. No recommended method is available for plain text files as there is no standardised export functionality for this format (the user can always create a new note using the file type they want on a case-by-case basis: Convenience commands for note creation).
