Modern integrated development environments offer a diverse set of features to improve code comprehension. However, varying interaction mechanisms and visualizations, as well as the on-screen distance between source code and relevant information can slow down programmers. We present INLINE, a stand-alone source code editor providing a novel concept called code-portals to embed additional textual content inside its main source code view in a uniform and non-intrusive way. We have adapted common code comprehension features and evaluated our approach in a qualitative usability study. A screencast highlighting the features of INLINE is available at: http://www.uni-ulm.de/en/in/pm/research/projects/inline.html
