Vim provides efficient window and tab management features. Window operations: :split or :sp to split window horizontally, :vsplit or :vsp to split window vertically, Ctrl+w h/j/k/l to move between windows, Ctrl+w q to close current window, Ctrl+w = to equalize window sizes, Ctrl+w +/- to adjust window height, Ctrl+w </> to adjust window width. Tab operations: :tabnew or :tabe to create new tab, :tabc to close current tab, :tabn or gt to switch to next tab, :tabp or gT to switch to previous tab, :tabfirst or :tabr to jump to first tab, :tablast to jump to last tab. These features make editing multiple files simultaneously very convenient and are an important part of Vim's efficient workflow.
