I was doing a bit of LaTeX this morning, and whilst fixing broken references I thought that there should be a better way to navigate the log files that pdflatex creates. And luckily some smart people have already implemented various tools to do so. Browsing CTAN I came across texloganalyser, which does a pretty good job at what I had in mind. Go check it out!
texloganalyser -ahouvw on your log file. These are the options I find the most relevant.
Also: I had the silliest idea ever. One could write a tool which turns a log file into a LaTeX file with proper layout and highlighting for code, and sectioning, and summaries, which you could then build to get the best log file reading experience ever.
