Martin, thank you for the answer!

Two months have passed... ☹️ 

Thank you! Very cool implemented! 👍 👍 👍 

There is some problem with "Selection to quote" option. If I open the comment form under some post, select some text, and click blue paste button, then the selection is inserting into the main Answer form, not into the comment form. Could you please correct this issue in next release? Thanks.
