hmmmm I guess what you're looking for is something like how Facebook works, you can drag and crop your avatar after uploading? That's something we'd love to have in the future, in the meantime just hang tight (and make use of your MS Paint )
@damien123 No additions needed, NodeBB loads the same whether you navigate to it "cold" (that is, directly via url), or locally via SPA interface. You can see that by viewing the page's source. It's indexable/crawlable.
If you're migrating, I'd encourage you to set up redirects so your links to existing topics/categories are not lost, but otherwise, you should be good to go.
