In version 1.3.12 of Glyphs a new feature was added to the preview pane of blurring the preview.

It's based on the way Wayfinding Sans Pro was designed: (see A new Design Approach)

The glyphs of channel letters was unique and it posted for the buildings or stores with LED lights that is more comfortable to view it.
