Every design is a thumbnail, so you recognise the piece before you read the name
Each entry carries a rendered thumbnail of the piece, its file name and the date it was last saved, numbered in order. Click one and it opens; if the file you are in has unsaved changes, you are asked whether to save them first.
The thumbnail is the point. A folder of files called RA-4897 and RA-5596
tells you nothing, and jewellery files are rarely named after what they look
like — here you find the ring by looking at it.
