By the way, with mosh we can have persistent shell over changing IP address, is there a text editor that would work with SFTP in a similar persistent way?

I mean, suppose I work on a project, close the laptop lid and some time later, open it. I might have a new IP, or in general the SSH connection might have been terminated.

In that case I would have to reload all the files in the project. Would it be possible to do IP hopping and maintain the SFTP connection unterminated?

I use Mac OS.
