New feature: Removal of devices unseen for 30 days

Sometimes when I reinstal system on one of my computers the old device is still on the list of devices. Right now on my list I have at least 20 devices when I have 7 working devices. As all my devices are introducers it’s not that easy to remove it from all Syncthings. It would be nice to have an option to set number of days after the device will be automaticly deleted if not seen. Also there can a new status on the device list that will show that the device is being close to deletion. For example, marked in red and countdown from last 3 days.

If those devices can’t be deleted, at least there could be an option to hide those devices and show only connected. Sorting by last seen could also be helpful.
