If it is `false`, then they will be converted to be `Pages` (e.g. simple notes, collected in `pages` folder).
 | ```taskOutputFormat``` | `ObsidianMD` or `StandardMD` | Output format of Evernote v10+ tasks. ObsidianMD will connvert tasks to match with Obsidian Tasks plugin's requirements. StandardMD will create plain tasks, loosing many features like reminders or due dates.
 | ```obsidianTaskTag``` | string | a tag to put to a task converted from Evernote v10+ tasks. Optional by Obsidian Tasks plugin, pls check the details there. 
-| ```trimStartingTabs``` | true or false | Removes the tab characters from the beginning of every line in a note. It is meaningful, because Obsidian recognizes tabs as codeblocks by default and blocks recognition of links (for instance) in the line

 Metadata settings can be set via the template.
