Allow merging of deleted code with a click on the arrow
Meld 3.20.2 on Win10.
One of the enormously useful features is being able to click the arrows when merging of code changes. One click - done!
However, when lines are deleted and I want to merge that change in, there is no arrow to click. Instead, I have to select and delete the block of code which takes more effort, with more mousing, scrolling and clicking involved. It would be great to have an arrow available to merge in the blank lines, with just one click. Removing code is a legitimate change, it shouldn't be treated differently.
I've included a pic for clarity. With the blue lines, there are arrows pointing in both directions but only forward arrow on the green lines.
