Okay, i was annoyed again, so I did a thing:
Windows doesn't previews .svg files by default in the windows explorer.
I needed some svg files for the AutoSizeText project https://github.com/SpielmannSpiel/AutoSizeText to create a new icon for it.
So I made an image viewer in @godotengine ^^"
Is anyone interested in such a thing? maybe even as a tool in #PEBI?
I think open sourcing this might also be a good idea.
