I use breakpoints when software supports it out of the box. Unfortunately, many third-party tools, IDE and Jupyter extensions in particular, are often of poor quality/WIP, are hard to use and can, at times, break my environment. For this reason, when a tool requires that I install additional packages, I am usually pretty reluctant to give it a try. Curiously, even seemingly simple tools, like variable explorers, are usually implemented relatively poorly in most IDEs. I like JetBrains's implementation most, but it isn't without issues. BTW, anybody has any recommendations for good and reliable, developer tool for Python and R?
