Enable Copy-Paste option from mouse & disable highlight after clicking Return

Hello,
First off, thank you for this brilliant terminal.
I want to enable copy and paste from mouse, even selecting a text in the terminal should copy the data, just like any other terminal. How do i enable that feature in WindTerm.
And, when I press Enter/Return key, it highlights the empty space, which really gets annoying sometimes. Please assist in disabling that feature too. 

Start by reproducing issue #3096 in WindTerm, checking mouse selection/copy behavior and what happens after pressing Return. Trace the relevant terminal input and selection entry points, then verify that selection can be copied as requested and that pressing Return no longer highlights empty space.
