When you work on a spreadsheet you can have a column like this:
1
2
3
Then you can drag it down and it automatically figures that each line you add is 4, 5, 6 etc… I’d really love something similar from Sublime. I constantly need it when developing (for example, when I want to add a bunch of options to a box). I know I can copy paste and then edit in multiline, but it doesn’t help if I want the values to be different. I’m currently not aware that there is any existing solution, so I’d love to see it coming
