Why did #Inkscape make it more difficult to chaneg the background color to transparenet, and since when?!??

It is now document properties, and pressing this unclear "Page" button as display?! no remove background color quick option!?

This is NOT a display property, but even export and printing!!!

@gbraad I think you're looking for the "Background Color" selector in the export dialog. The one in Document Properties was removed relatively recently.
@pulsar17 I do not use the export from the UI. The files needed to have the correct setup, otherwise they would not convert as expect. @doctormo was super helpful. These files were older ...
