It would be nice to have Awful.app use the default browser configured by the user on iOS instead of opening links up with Safari.
Apple has allowed changing default browser since iOS 14 - I can't really speak to how easy (or not) this change would be to work out, but it would be a super nice enhancement imo.
If I'm using Firefox Focus or DuckDuckGo Browser it doesn't come up as an option in the settings:

Steps to reproduce
- Launch Awful.
- Click the settings gear
- Click "Default Browser"
- Regardless of if any other browsers are installed, you will only see options for "Awful" and "Safari"
Expected result
Other browsers installed on iOS will show as options
Observed result
I'm going on Safari
