Editor
Rich editor
Preview citations, file inclusions and images when your cursor hovers over the command.
Drag and drop any file from your Desktop, or any marker in the outline, to the editor and Texpad will insert the include command for you.
Latex aware spellcheck will highlight spell errors, but not LaTeX commands.
Snippets
Snippets make it easy to insert common chunks of LaTeX code, access them from the snippets menu, and add as many as you need.
