It has a fuzzy file finder present, that makes it easier to look for files inside the working directory. Also, "goto" worked for me, and hence i use that. i have a wide variety of .deb packages installed and they were contradicting the "g" tag. If you like something else, just modify your .bashrc alias or open install.sh and modify the alias value being written there. That is a minute difference.
Also, another difference between bashmark and this is that it uses all functionalities as an extension to goto. ie. to save you write" goto -s <shortcut> " instead of "s <shortcut>" this is again done to simplify the .bashrc and remove g/s/l/p functions from being created. Gives me greater control.
Also - if the purpose is to save as much typing as possible, why it isnt a bit shorter command than 'goto'? .)
