- View top contributors of the app binaries

Once the analysis has been completed, you will see a breakdown of your application binary, highlighting what kind of files are taking the most space.
A Files view shows you what files contribute to the app size the most so that you know where to start optimizing it.
In case of regressions (i.e. someone adding a very large file), Maestro Cloud will block a pull request and surface what are the offending files.
In case of improvements, Maestro Cloud will surface how much.
By default, an App size increase of 8% is considered a regression, and an App Size decrease of 10% is considered an improvement. It's possible to configure those parameters in your config file.
