Is it possible to have Notepad++ show two rows of file tabs?
I wasn't able to find such a setting.
According to the documentation Wiki:
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"
