Is it possible to have Notepad++ show two rows of file tabs?

According to the documentation Wiki:

• When more tabs that can fit on the view are displayed:
  • if Settings -> Preferences -> General -> Tab bar -> Multiline is checked, several rows of tabs will stack. Clicking on a tab brings to the bottommost row the whole row of tabs
  • Otherwise a pair of small buttons pointing left and right will show, and clicking them will move through the imaginary row of tabs. The triangles show up and down if the tabs are arrranged vertically.

This was definitely an SU question, not SO where they would have laughed and pointed and sent your question here.

STEP 1: Settings -> Preferences... Will open Preferences window.

STEP 2: Find the "Tab Bar" check-box group and check "Multi-line"
