A common complaint I've had about using QB for Neovim is that it's really difficult to find out what went wrong on the build overview page. Our repository is being watched by 14,000+ people, and we have nearly 200 contributors. Most of them are not intimately familiar with the build systems, and so it's really important for them to be able to find out what went wrong and quickly from the build overview page. The net affect is that it can leave an overall poor impression on an otherwise good tool.
