I think you’ve got a very good point and this definitely needs further discussion. The simplicity / minimalist UX folks will argue this. Some also might say that this isn’t a hyperlink issue but a browser issue. My current browser(s) all allow current window, new tab, new window within the right click menu and I’ve grown very used to doing so.
I’d really like to see this implemented via JS/CSS in a demo and play around with it for a few days on some popular websites and see how I like it.
Either way, great job!
