I have bad eyes.
and can i change gizmo arrow color?
it looks like transparent.
i can not found gizmo color setting in editor setting.
What version of Godot are you using?
I'm in 3.0.5 and I found all of what you mention, except for gizmo's color. They are in editor settings, the editor font is in Interface>Editor, while the gizmo's size & opacity are in Editors>3d
thanks for comment.
my version is v 3.0.6.
Font size resolved
But Gizmo's transparency does not change
sorry,gizmo color enabled after restart.
