I’ve been using the flatpak version of Obsidian on Elementary OS(Linux). I use a theme called by miniman by a GitHub user named @kepano.
This is the link to the css to that theme. (https://github.com/kepano/obsidian-minimal/blob/master/obsidian.css)
This theme makes the close, and maximise buttons dissappear. I have to close the app using keyboard shortcuts.
Can anyone suggest some changes to the css code to make the close and maximise buttons appear??
