How much can be done with the title bar icon?

Plugin and Widget API
1

My plugin’s icon is black with no background, which makes it invisible in dark mode. I will add a white background, but I have some questions:

  • is the plugin icon only set on the publishing page?
  • is it possible to change the icon at runtime?
  • is it possible to have NO icon? (my plugin’s icon can be typed with Unicode, so if omitting the icon would omit the space it takes up, I could just type the icon and it would look correct in both modes)

It is not possible to change the plugin icon with the plugin code, because the icon is not part of it and is loaded separately (via the plugin’s publish/edit window).

The icon is required. Without it, you will not be able to publish your resource.
