The mod is pretty bad, but I decided to publish it anyway; maybe someone is interested.
It checks your crashlog.txt and looks for matching strings, then it prints out the values in the chat (set a keybind for it).
Additionally, it prints out the lines of crashes that did not fit any category. You can manually check them in your crashlog.txt if you want.
The Lua file is commented, so you should be able to easily understand it and change it to your liking if needed.
C++ crashes are mostly mod-related but not all of them, so keep that in mind. (By default, it all goes into the ModCrash category.)
Mod goes into mods.
