FR: Support For Minimal Theme

[greetclammy]

At the time of this FR, the Minimal Theme is the single most popular custom theme in Obsidian w/ 1,174,109 million installs. It is not purely cosmetic, but also adds a ton of enhancements that the default theme lacks. Given its status as a mainstay in the community, its vast adoption rate & its semi-official status due to being published by the CEO of Obsidian himself, please add full support for it! 🙏

'Outliner' is among the very few plugins that "have received special love and attention" by the Minimal theme. 'Outliner' should give some love back! 🥰
