[Feature Request] Export/import lists as markdown files #6
Description
Add the ability to export and import the lists and list items as markdown files in folders. Exporting each list as a folder and each item as a file would be very intuitive. The folder would be the list name, the file name would be each list items title, and the file contents would be the description of the list item if it has one. The exported data would be contained in a folder named something like minttask-2023-22-10-450 meaning the exported data would automatically be named based on the date and time it was created. This makes managing backups easy. This system would be straightforward to implement if minttask stored all of its data as markdown files on the filesystem by default. In that case importing and exporting the list(s) would just mean copying and pasting a directory.
