## DONE [A] `#+OPTIONS:` toggles supported by `go-org` tag1 tag2

`go-org` supports multiple export toggles as described in the export settings section of the Org mode manual. By default (most of?) those toggles are enabled. This file starts with `#+OPTIONS: toc:nil f:nil e:nil` and thus disables the table of contents, footnotes & entities. That means, entities like `---` --- (mdash) will be left untouched, footnotes like `[fn:1]` will not be exported and there won't be a table of contents at the top. As buffer options are merged with the defaults, the above headline will be exported with priority, todo status & tags.
