I shared a Markdown file, but it seems he didn't open it with the TXT tool. Instead, he opened it with the whiteboard tool, then closed the whiteboard, and it opened with OnlyOffice. Only after closing the filename dot did it open as a TXT file. Is this a bug? The Markdown tool should default to opening and editing with the TXT plugin.
