Is there a way to toggle settings from some kind of command line or command palette? There are some settings I need to have on and off here and there like readable line length
I know I can open the settings page with a shortcut etc but I am not always in that particular section.
No and such plugin to change settings using some uri scheme would be quite useless since different vaults can be used to encapsulate different set of settings. You can use Shell commands plugin to define shell commands that operate json files in .obsidian folder. The concept of toggling settings on-the-fly isn’t possible in Obsidian since usually settings are loaded at vault startup.
