What does the orange x/paperclip icon mean in settings?

In some settings for 3D printing in Luban an orange icon that looks like a cross between an X and a paperclip shows up to the left. What does it mean? There is no help for it, no documentation, and no mention of it in this forum that I can find.


It’s a “chain link.” When it is orange and X’d out, it means that the setting has been “unlinked” from other settings that it normally auto-follows along with. In this case, line width is usually linked to the size of your nozzle (a 0.4mm nozzle normally has a line width of 0.4mm, but here the line width has been manually changed to 0.5).
