Pros
Pro Notifications include details
Most clients use notifications only to inform you of the fact that there's a new item that needs your attention, but Polly also includes the item in the notification, allowing you to decide with a glance at the notification if you wish to take action.
Pro Best UI of all Twitter clients
Pro Plays movies and shows images in-line with the tweet(s)
Even movie types that chrome-based browsers on Linux do not play are shown.
Images of retweeted or liked tweets are shown in-line too.
Cons
Con Out of date
More than two years since the last code commit, this app will fail when Twitter changes their API.
Con Can't view full-sized images in within the app
While the app can show previews inline, to show full images, they are opened in a browser instead of being opened within the application.
Con Unpleasant UI
Con No live update
No live updates anymore. You have to close and reopen the program to see new tweets.
Con Borderline outdated
According to the installation: Warning: runtime/org.baedert.corebird.Locale/x86_64/stable is end-of-life, with reason: Vital Twitter API endpoints have been retired and as a consequence, Corebird is unmaintained and will not work in the future.
Con No ability to change the tiny font that it uses
Absolutely no ability to customize UI. Completely unusable on high DPI displays.
Con Not for infinite scrolling
After showing a limited number of posts, the infinite scrolling no longer works with an "too many requests" error.
