I often upload eBooks to HubSpot, many of which have internal links. I noticed that when you click on an internal link of an ebook it opens the link in place of your ebook, instead of a new tab. I know you can just right-click and select "open in new tab", but many people won't do this and I do not want to take away the immediate focus of the person reading my ebook. HubSpot should have a way for the internal links to open in a new tab for the readers to have a more seamless experience.
