Pretty much any software that generates starcharts (eg: stellarium) will show you the actual positions of stars (as seen from earth), considering things like proper motion. That said, this is a high precision thing, so might be extremely non-obvious (Barnard's Star is only 10.3"/year).
We are currently in the process of getting high enough precision to get proper motions for nearby galaxies. Using radial velocities alone could certainly make things misleading, and a lot of large scale maps of the universe tend to prefer going by redshift instead of making additional assumptions about how the universe has expanded.
Hello u/frustrated_staff, your submission "Universal maps of where things actually are now" has been removed from r/space because:
Such questions should be asked in the "All space questions" thread stickied at the top of the sub.
Please read the rules in the sidebar and check r/space for duplicate submissions before posting. If you have any questions about this removal please message the r/space moderators. Thank you.
