Thanks @bullshark!
I'll certainly work arrows into those icons to see how they fit, or perhaps reconsider their design and create something similar to the Bitcoin Core screenshot you shared over on Slack - thanks for that! I also have an alternative version of the PoR icon without the logo - in fact, I have variants of that icon in just about every shape flask you could imagine too, haha. Gotta love a good Erlenmeyer flask though ;)
Anyway, I digress - the real beauty of switching over to .svg icons is in their adaptability - they're easy to replace and easy to re-colour, so it becomes very simple to tweak the designs going forwards should we need to :)
Vectors are great.
