Download Harmony from the website.
Please indicate your operating system, Harmony's version and if you can, steps to reproduce the bug.
Also, please include the log of Harmony (Cmd/Ctrl + Alt + i, console tab).
Altough you can submit feature requests, keep in mind that I only prioritize requests coming from paying users.
Harmony used to be an open-source software. It is now a free-to-evaluate software, but you need a license for continued use.
I explain this decision here.
You can still access the source code prior to the 0.5.0 release on this repo.
