how to remove code blocks with a simple click

["radovan bast" <radovan bast irsamc ups-tlse fr>]

dear meld developers,

first of all please let me thank you for a great piece of software!
i am using meld on a daily basis:
for diffs, as git difftool, as git mergetool.
what i love about meld is the simple, clean, predictable interface.

there are these nice arrows that allow you to synchronize code blocks
very easily. but often i have the situation where "left" is nothing (HEAD),
"right" is some code that i want to remove before committing,
for instance some debug code (working tree).
for this it would be nice if i could remove the code block to the right
with a simple click as well. in other words i am looking for an arrow
above the "nothing". it seems that i need to mark the code that i want
to remove and delete it manually.

is there such a simple functionality?

i am sorry if this has been asked/suggested before - i admit that i haven't
browsed the archives.

thanks again and best wishes,
  radovan
