Deprecate in favor of vim-tabdrop
Jumping with tags in vim is a pain if you are used to tabs. TagJump open a new tab (or go to the tab already opening the file, i.e. tab drop behavior) when you jump with tags. It also automatically close the tab when you jump back with <C-t>. This prevents you from creating duplicate tabs when you jump to the same file multiple times.
Install either with vim-plug, Vundle, Pathogen or Neobundle.
