Well, from past postings, you know what I feel about web authors taking control of how links open. (It is a hateful practice!)
I feel very strongly that it is for the visitor to control whether a link replaces the the contents of the existing window or opens in a new window or tab.
While you may think you proposal will ease the situation, it makes things far, far, worse for the visually impaired and others who cannot easily follow what is happening when links open in unexpected ways.
It really is down to users to obtain appropriate software for their needs and learn how to use it.
Volunteer Helper - but recommending that users move off the platform!
