Hi LordMiguel.

Just letting you know that you can get the quality icon sprite thingie to show only in alt-mode by adding this one line in the draw_sprite function:

only_in_alt_mode = true

Basically ends up looking like:

local quality_icon = rendering.draw_sprite{
sprite = "quality." .. quality.name,
target = plant,
surface = plant.surface,
target_offset = {0.0, 0.0},
x_scale = 0.5,
y_scale = 0.5,
render_layer = "light-effect",
only_in_alt_mode = true
}

Thanks for the mod and have a great day.

Thanks! I have implemented the change in an update!
(I had been meaning to investigate this so this is super helpful!)
