Earlier quoted context omitted.
Sublime does keyboard macros that make my life easier which VSC and its add-on don't have. Now if Sublime had a option to delete trailing whitespace every time I hit return, I could return to my PFE days of macro productivity. When I start doing coding and text manipulation again, it looks like it will be Sublime I purchase.
Sublime has the settings: `trim_trailing_white_space_on_save` and `ensure_newline_at_eof_on_save`, I found these very satisfactory. But there's almost certainly a ST extension for your particular taste.
I actually want it to trigger on each line when hitting return. It really helps with macros you can write when text munging. I didn't spend as much time as I would have liked looking at each editor but a command-key that deletes all ending whitspace on a line would also be acceptable.
