Support for rendering Markdown files (.md) properly in Resilio mobile apps would be great (including support for Pandoc's grid tables: https://pandoc.org/MANUAL.html#tables).
I'm increasingly using MD in place of TXT and RTF. Currently Resilio for iOS reads MD files as plain text, rendering the source code only.
In the longer term editing support would be great. Plus support for interlinks and backlinks would also be great, so we can effectively create Wikis within our Resilio folders.
