"A lightweight web browser based on Dillo but with many improvements, such as: support for http, https, gemini, gopher, epub..." <- It says that in the project description... isn't that weird that it claims Dillo doesn't support HTTP and HTTPS? Also,
https://dillo-browser.github.io
says it has plugins for gemini and gopher. What's the rationale for dillo-plus then? 8-\
