Unified Issue Reports
Most app pages has a "Report an Issue" button, which allows you to report about bugs and issues, but, when you click on this button, it opens different websites, like GitLab, GitHub, Bugzilla etc. To report about issue, you always must register an account on these websites, which takes precious time, or completely discourages you from reporting about bug.
Why not make a unified issue report system? For example, work is already underway on the implementation of unified payments and donations for GNOME Software, so something similar could also be implemented for issue reports
