The ability to take a list like:

Test1,Test2,Test3

And, by using multiple cursors, in seconds you can turn it into:

~/DoThingOn Test1 --reallywell
~/DoThingOn Test2 --reallywell
~/DoThingOn Test3 --reallywell

...except with a list that's 500 items long!

Visual Studio Code (command+fn2) and Sublime support this as an example of how it works. They just lack the clean visual style of Textastic.

Thanks.

I'd prefer to have my ftp service separate to the editor; it's a tough nut to crack with permissions and all so really belongs in SSHFS or Cyberduck, etc. All FTP clients offer an open in editor of choice feature.
