I would like to suggest two features that could significantly improve the AntennaPod experience:
1. User accounts and synchronization
It would be great to have the option to create an AntennaPod account, either with an email address or through Google Sign-In. This would allow subscriptions, listening history, playback progress, and other settings to be synchronized across devices.
This would be especially useful when using AntennaPod on multiple devices or when switching to a new phone.
2. Web Player
A web player would also be a very useful addition. Sometimes I listen to podcasts while working on my PC, and it would be convenient to access my AntennaPod subscriptions directly from a web browser.
With an account-based system, I could simply log in through the browser, see my subscriptions, and continue listening from where I left off on my phone.
I think user accounts + synchronization + a web player would make AntennaPod much more convenient for people who listen to podcasts across multiple devices, while still maintaining the simplicity and open-source philosophy of the app. Sorry for my english.
