Feature request: more information from Syncthing integration

I’d like to have some information about devices and folders from Syncthing in Home Assistant.

Use case: I want to set up a notification if a device hasn’t been active for a while or when a folder has a certain size.

When looking at the source code, I see the folders are already available as an attribute, but not as a sensor. If someone can help me with changing this to real sensors, please let me know. While I have no experience with developing in HA (and no Python experience, but with JS/PHP) I’m happy to learn.
