I agree there should be a dedicated "crop to selection" feature even though Designer is not intended to be a dedicated photo editing program. I'd love to have Designer be my one tool for daily "drawing/painting" tasks. Obviously, if I need really sophisticated photo editing, I'd use a dedicated tool, but cropping is a *super* basic feature in my opinion.
At the very least, if I select part of an image with the rectangular marquee tool, it should copy what's selected, not the whole image/layer. I've never used a drawing/paint application in my life that doesn't copy the current selection to the clipboard. It's making me wonder if I'm doing something wrong or missing a trick. Anyway, if copying the selection were possible, we could achieve cropping with Ctrl+C then Ctrl+Alt+Shft+N.
EDIT: I think I get it. The layer needs to be rasterized, then what is selected with marquee will be copied properly to the clipboard.

I'm sure Opera is great, but it looks as though https://cloudconvert.com/svg-to-pdf might be the right tool for the job. I just tried converting one of my troublesome SVGs to a PDF and dragged it into my AD canvas. Worked well. I'd rather not have to go through this extra step, but it'll do for now.

Is AD's SVG parser unable to properly interpret transforms?
This very simple SVG is showing properly in Chrome, Internet Explorer, and PowerPoint, but in AD, the path is incorrectly positioned so part of it is outside the viewbox:
<svg width="27.1" height="27.2" viewBox="-13.5, -13.5, 27.1, 27.2" xmlns="http://www.w3.org/2000/svg" version="1.1"> <path d="M0,-440 L0,-420 A420,420 0 0 1 14.7,-419.7 L15.4,-439.8 A440,440 0 0 0 0,-440 z" transform="translate(-7.5, 429.9) rotate(44, 7.5,-429.9)" stroke-width="1" stroke-linejoin="round" stroke="red" fill="red"> </path> </svg> What it's supposed to look like:

What it looks like in AD:
 
If I edit in AD, I get this:

 
It would be nice to know if Affinity has plans to fix this.
