Line numbers

[ThomasMLS]

I would like to have some text or information appear that tells me the number of lines, in one of the forms below (if not both):

• at the bottom that tells me how many lines of text I have highlighted.

• on the far left side that tells me the line number.

The calculation for finding the line number (whole lines) could for example be to do integer division on the "Length" field at the bottom with the "Bytes per row" field for the second method described above.
The first method described above could use the whole lines method and a partial lines method which calculates the "Length" field modulo the "Bytes per row".

My need for this feature request is efficiency; it arises when I work with other "Bytes per row" values than 16 and I highlight a huge portion of bytes or characters and want to save time by not doing the calculation myself; it could theoretically be compared to not having the "Length" field altogether, causing some extra work to work out how many bytes one have highlighted, for example.
