I just started using Affinity Designer and I found one thing that significantly reduces my productivity (comparing to Inkscape). It is related to export of the vector image into multiple resolutions.
On Android it is very common that one vector image is exported into multiple resolutions. Eg. launcher icon is exported into
<project home>res/drawable-mdpi/ic_launcher.png with resolution 48x48px
<project home>res/drawable-hdpi/ic_launcher.png with resolution 72x72px
<project home>res/drawable-xhdpi/ic_launcher.png with resolution 96x96px
Using Inkscape I made script exporting single drawing into multiple files. Is something similar possible with Designer?
