Having the option to customize widgets with custom data sources (Webhook called every X amount of hours/minutes, API, DB, local or cloud text/image file,...)
It could also act as a button to trigger a set of actions.
There's a lot of room for customization especially if the widgets became interactive with the next OS release, I could have multiple buttons per widget that display some information with real-time updates,...

The next non-alpha BTT release will finally come with the "floating menu feature". These can contain all sort of widgets and can be placed anywhere on your screen. However they will not integrated into the notification center.
Currently implementing optional auto-hiding for these:
Having them in the Notification center will be a game-changer! They'll be accessible everywhere. As for the other option, you have to be on the desktop to interact with them.
But it is really really close to releasable alpha state now.
