Yes, it can be really jarring to have to constantly move between several small files. I mostly use C#, and a while back I settled on a middle ground, where closely-related classes and interfaces are grouped together in a single file. When I'm working on web apps/APIs, I usually follow the "feature folder" concept too, where all the most central parts are together in the same file.
