The current definition of IconName is just type IconName = string. This makes it impossible to use autocomplete in our IDEs.
I’d like to suggest the following definition instead:
type IconName =
| 'lucide-chevron-left'
| 'lucide-chevron-right'
| 'lucide-chevron-up'
| 'lucide-chevron-down'
// more Lucide icons...
| 'links-coming-in'
| 'links-going-out'
// more Obsidian-specific icons...
| (string & {});
This way, we can take advantage of our IDE’s autocomplete while allowing custom icons defined by addIcon.
