Detect .bike and .opml in plain text means two things:

  1. You can copy .bike or .opml text from a text editor and paste it into Bike and it will be read correctly. If Bike cannot read either of those formats then plain text will be pasted.

  2. You can use alternative file extensions (.html for example) for your “bike” content files. If Bike content cannot be read from the file then the content will be opened as plain text.
