Hello
It is very cool to have a "Parallel" button. We can easily change the same parallels.
But there is no feature to "Ad" one of the parallels as a separate tab which is then also right away tied together.
Logos

Same in Accordance to change quickly to a parallel corpus.
But Accordance has also an "Ad Parallel" button which opens a new tab with the same corpus and it is right away tied together.

I see no such feature in Logos/Verbum
