automated crash reporting. Unfortunately it's a pain to build but this is single most important thing you can do to improve quality of your software... On the server, process those files and generate web pages for easy viewing of the crashes.
I'm not a developer but I would think sharing what you can of your implementations of these would benefit others as well. i.e. good examples of exception handlers to catch crashes in the app, in crash handler download symbols from the server to get readable callstack, create a crash report that includes callstacks of all thread, program and os information
and possibly any implementations of the processing of the files
Possibly these are just blog posts intended for the junior developer or actual github repos. Thanks for all your work!
