Hi Ryan, thanks for your feedback.
In relation to the Preview option I'm assuming you're using a PC and you're wanting to preview an SVG?
The reason you cannot see the SVG is because it is not a feature in file explorer for Windows (you can see them on a Mac as it is a feature).
On an earlier version we had our own GUI that allowed you to do this, however the general feedback was that it was slow and not very helpful.
If you are using a Windows PC and want to see a thumbnail of the SVG files, this Instant Answer will assist you.
We have a few feature requests regarding the zoom and percentages which are currently with the development team for review which is an area we hope to improve upon in the future.
Thanks for the clarification on the Idea and apologies I did not understand the initial request.
