Is your feature request specific to a certain platform/environment? Please specify.
Maybe universal.

Is your feature request related to a problem? Please describe.
At present, regardless of whether it is under the standalone application or the Plasmoid, the "Recent changes" can only display the ID of device and directory instead of name like Web UI. This is inconvenient for use cases that only use names to identify devices and folders.

Describe the solution you'd like
Provide an option to allow people to choose whether to display ID or name.

Describe alternatives you've considered
Modifying the ID when creating a folder is the same as the name, but it seems that the device ID cannot be modified because it is generated.

Implemented on master. It now shows the device name if known.
