add offset to delete characters

[mrintegrity]

Would be nice to add an offset from the end of the line, from where it would start deleting characters.
something like this:

"this is a string"

delete(1,7).type("my")

"this is my string"

I do like this idea... will keep it in mind for a future release.

Any update or plans on when this could be implemented ?

If we want to implement ourself, can you point us to the right line of code where we should be looking at ?
