Possible features to add for Samsung devices.

[Jahan02]

I would like to request that you make these certain features available for all Samsung users:

 1. Allow for the ability to lock notifications. For example, having certain notifications that you don't want to swipe accidentally to be labled as 'Priority Notifications', so the user doesn't swipe it by accident. Also, allow for them to be set as 'Unprioritised' as well once the notification is no longer a priority. 

2. Essentially the same with notifications but also for when apps are open but not used allow for them to be locked or unlocked so they're no accidentally swiped away.

Try the NotiStar module as part of the Good Lock app (available from Galaxy store). It might just have this feature.

It's possible, but maybe not for everyone, Barclays app and another I use had "persistent notification".
