Like in the title, env "$EDITOR" var is being ignored. $ echo "$EDITOR" `micro` PREFIX + C-f file selection and open with C-o produces: `vi -- "~/.tmux.conf "` When i open it with just 'o', it opens up in **sublime-text**. Not sure if that matters - this is done via ssh on remote, but both pcs have same "$EDITOR" and tmux.conf set.
