## Qualifications

There are a ton of great Python projects out there, but what makes an
application "Awesome™"? Please check that all of the following criteria apply:

- [X] Free software with an online source repository.
- [X] Using Python for a considerable part of their functionality.
- [ ] Well-known, or at least prominently used in an identifiable niche.
- [X] Maintained or otherwise demonstrably still functional on relevant platforms.
- [X] An application, not a library or framework.

Note that installability via pip/PyPI and a developer-audience focus
may warrant a higher standard for inclusion, in keeping with the
spirit of the list:

## Additional notability info

It's amazing to use. As soon as I copy a YouTube link in my browser, the program picks it up and begins downloading. It's SUPER well polished. GUIs are rare-ish in Python. This one is multi-windowed with lots of stuff going on. Impressive looking.

The developer has been spending a lot of time recently adding and polishing features.

## One more thing

Since you've made it this far, why not consider filing [a PR](https://github.com/mahmoud/awesome-python-applications/pulls)?

If your suggestion is a GitHub project, it's as easy as adding 2-3
lines to the `projects.yaml` file. There are comments and plenty of
examples in the file. Here's [an edit link](https://github.com/mahmoud/awesome-python-applications/edit/master/projects.yaml).

No pressure or anything, feel free to smack that submit button, too! Thanks again!

Read projects.yaml and nearby entries, along with the qualification checklist in the issue. Verify whether PyIDM meets the list's criteria, especially the unchecked notability requirement; done means an accepted project is represented by the appropriate 2–3-line entry in projects.yaml.
