The build pane on the bottom-right gives you access to all the Leiningen commands to run, build, and test your project. With the embedded lein-typed
plugin, the 'Test' button will automatically run type checking on projects that use Typed Clojure. Additionally, if you click a project.clj file, you'll see a 'Check Versions' button which will run lein-ancient
to look for new versions of your dependencies.
The editor pane also has several integrations. In addition to syntax highlighting, Clojure and ClojureScript files also show a 'Doc' button which enables code completion thanks to the integrated compliment
library. There is also a 'Paredit' button, which enables the self-described mode
which completes parenthesis and adds advanced editing behaviors.
