The Simple Template Importer plugin simplifies the process of installing template vaults into your existing workspace by allowing direct import from ZIP files. It automatically places markdown files, CSS snippets, and other template elements in their correct locations within your vault, eliminating the need for manual file management. This is especially useful for users frustrated with the multi-step process of setting up templates, CSS, and configurations manually. The plugin also supports optional import folders and file overwriting to handle conflicts more efficiently, aiming to bring a Notion-style one-click experience to Obsidian.
