The Jira Linker plugin enhances your Obsidian experience by enabling seamless integration with Jira. It provides commands to quickly generate web-based URLs or local file links for Jira issues, supporting multiple Jira instances. Users can configure their Jira instance URLs, set a local directory as the root for issue-related files, and customize the default 'main' file name. The plugin allows you to highlight a Jira issue in the editor and link it with a simple command, or input an issue identifier manually. This functionality streamlines access to Jira-related information within your notes.
