Customize update frequency per podcast.
There are certain podcasts that I don't want to check for updates every time the auto-update runs.
Either because the podcast is finished, and I only want to stay subscribed in case the podcast will use their feed to deliver me news of a new, similar podcast they're doing.
Or it's that I know that the podcast will not update more than a few times a year.
Would be cool if I could customize the frequency for each podcast. The same way I can disable updates altogether for certain podcasts.
You could justify this feature as part of an initiative to allow cutting back on battery/cpu cost.
There could also be an advanced option, where the app tries to predict the time a podcast updated, by looking at previous release times.
Additionally, you could use other people's anonymous data sharing, to see when a podcast has updated, and then send push notifications to all users that subscribed to that podcast with the update frequency set to "On-Demand"
Another use case:
I am subscribed to hundreds of podcasts. Most of them, if a new episode is downloaded, I will listen to it eventually. I would ideally want the app to check for updates daily, so that it can download them overnight.
However, there are one or two that I want to listen to as soon as possible when they are released. The sooner the app gets the updates, the better.
For this reason, I have configured my app to check for updates hourly. It will check all 300 podcasts, on the off chance that this one particular podcast has updated.
It would be much preferable if I could have it check only that one particular podcast hourly, and then update all the rest daily with a single global setting.
Or just allow us to set a time to check for a specific podcast. I know when most off my podcasts update, so unless I go in and manually update it can be a few hours before my full update kicks in.
