i like to sort my vifm buffers by modification time but don’t like the fact that all the directories are grouped first and then the files next. i wanted to sort the buffer so that there is no distinction between directories and files when sorting by modification time. here is how you can achieve it.
issue the colon(:) to access the vifm command prompt
then issue the following command
mtime is for modification time and dir for directories.
i have mapped that to the leader key+s combo in vifmrc file thusly
nmap ,s :set sort=mtime,dir<cr>
