This is from the Installatron FAQ:
" Can I recommend a web application be added?
Absolutely. We’re constantly evaluating new web applications for inclusion. However, only the best applications are accepted; applications that are complicated to use and applications that do not offer unique functionality complicate the website owner experience and are therefore avoided. It’s also important that applications have at least a few mature translations available as Installatron Plugin is used worldwide.
To make a recommendation, open a ticket. Be sure to include a summary of the advantages the application provides."
