Covcov was built to solve the hassle of checking coverage reports from istanbul.
I found it a massive pain in mono-repos to be often navigating to the coverage/lcov/index.html file inside each package folder.
And out of the box you don't get the full coverage metrics for the whole monorepo.
Covcov gathers all coverage reports it can find in subfolders and renders them in a unified tui.
This means it's easy to run jest -w in any package folder and run covcov in the root to see how
the overall coverage is updating.
It has a table view of all folders and file changes, and a file view to dig into which lines are missing from coverage.
