For a while, the Lwarp manual had a troubleshooting section which gathered many issues and solutions together at one place. This became hard to manage, with duplicate information and limited sorting.

It became obvious that the LaTeX indexing system would be a better way to handle the numerous problem/solution combinations which were being documented. The resulting troubleshooting index is easy to manage, and is sorted several ways according to how a person might think to look up the problem, including separate entries for any related keywords, error messages, and related packages.

As of this writing, there are almost 600 entries in the troubleshooting index, and 400 in the general index, as well as the very large automated index of LaTeX objects. (And figuring out how to get splitidx to work with a DTX file was "interesting".)

Give it a try, and suggest any ideas for improvement.
