Configuration parameters are ignored in some instances, or the configuration themselves could be more logical.
An example is the project-directory parameter, used to define where project's data for funding can be read from. The service used it for reading data, yet goes on to create a var directory for other reasons. The other reasons are not configurable.
REPORTED RESOLVED FIXED
Reduce friction for new contributors by having clear documentation accessible about key concepts of the project. Maybe include a walk through.
It appears possible to encode this amount into the QR code. It makes things easier for the user and helps avoids mistakes in amount to send.
Associate the expected amount to receive to avoid potential legal issues with people sending very large sums.
Give access to a wider variety of users by hosting binaries for popular platforms. Publicize checksums and possible PGP signature.
The project URL uses the Project's name, which can be capitalized and have spaces. A better format would be all down case, filter weird characters, and remove spacing.
Add rate limiting and other mitigation to protect against anti-social people.
