I recently stumbled on AWS Cloud9 and Spacemacs and genuinely impressed with both of them.
The problem is I cannot make Spacemacs to work properly on remote environment development just like Cloud9, all this time I was using VSCode with Dropbox and sync with local folder.
I tried with ftp, X window, dired remote mode (and similar Remote VSCode in the VSCode extension), none is satisfactory. I need it for all the full-blown features, remote code listing, debugging, versioning (I use mercurial).
Spacemacs is more than ok in the local development and I think VSCode just need to take a liitle more steps to rule them all.
