Transparent colour for icons

I noticed that you use the fist pixel downleft to define a transparent colour for icons. That`s useful when you work with an indexed palette like Gif only. But i use truecolour PNG for the icons. And don`t need it. In fact it disturbs me. It may happen that i accidentally touch this first pixel downleft. Could you please implement a way to turn off the use of transparent colour?

I have no control over it.

Ah, that`s a shame. Nevertheless thanks for having a look.
