I find it surprising that in 2014, most of the tools we use to read code treat it mostly like any other text. With the exception of some IDEs for some languages (e.g., Eclipse and Java), very few apps for browsing code actually understand its structure, i.e., the hierarchy of symbols and namespaces and the implicit graph defined by module imports, function calls, type references, etc. We're relying more and more on external, often open-source libraries, and are therefore spending more and more of our time reading through other people's code. Yet the tools don't seem to have caught up.
