      Have you tried “cloning”, vertically adjusting the offset of the clone per your window size, and then syncing the vertical scrolling of the two views?

          Best way to understand it is to try it:

          • right-click a Notepad++ tab for a file
          • choose Clone to other view in the resulting popup menu

                Would it be possible to add feature:
                Clone to other view sets right view first line as last line of the left view + 1 automatically ?

                  Probably not reasonable as a feature addition.
                  Probably very doable as a script.

                    Here’s a barebones PythonScript that shows how this could work:

                    notepad.menuCommand(MENUCOMMAND.VIEW_CLONE_TO_ANOTHER_VIEW)
                    editor2.setFirstVisibleLine(editor1.getFirstVisibleLine() + editor1.linesOnScreen())
                    notepad.menuCommand(MENUCOMMAND.VIEW_SYNSCROLLV)
                    

                    Because Notepad++'s View menu’s Synchronize Vertical Scrolling choice is a toggle, however, the above only works if it is currently off. This is a problem with a few Notepad++ menu commands and scripts.

                    I wonder if @Ekopalypse has some ideas about some script code that can read the status of a checkable menu item? Ideally it would depend only upon command-id (e.g. 44035 in this case) and not the text of the menu item (to avoid problems with using N++ in a different localization).

                      I ASSUME i can be done using GetMenuItemInfoW and MENUITEMINFOW. Will follow up later, probably tomorrow.

                            I turned your script into the following recursive function that finds a specified id:

                            def menu_search_for_specified_id(menu_handle, id_to_find):  # returns ( direct-menu-handle, position-on-menu )
                                menu_item_count = user32.GetMenuItemCount(menu_handle)
                                for menu_pos in range(menu_item_count):
                                    sub_menu_handle = user32.GetSubMenu(menu_handle, menu_pos)
                                    if sub_menu_handle != 0:
                                        (h, p) = menu_search_for_specified_id(sub_menu_handle, id_to_find)
                                        if h != 0: return (h, p)
                                    else:
                                        mii = MENUITEMINFO()
                                        mii.cbSize = ctypes.sizeof(mii)
                                        mii.fMask = MIIM_ID
                                        mii.dwTypeData = None
                                        lpmii = ctypes.byref(mii)
                                        user32.GetMenuItemInfoW(menu_handle, menu_pos, True, lpmii)
                                        if mii.wID == id_to_find: return (menu_handle, menu_pos)
                                return (0, 0)  # nothing found
                            

                            I’ll keep going with a final solution for the OP’s request, that uses this…interested parties please check back later. :-)

                              • You can Clone the text document to the other view. (Dual View).
                              • Scroll down to about page length.
                              • And then use Synchronized Vertical Scrolling feature to have Two-Page View in Notepad++.

                              This is not a fully automated feature but one that you can do it very easily.

                              This video shows how you can use Synchronized Vertical/horizontal scrolling feature in Notepad++. Hope it helps.

                              (disclaimer: I am the owner of this Notepad++ YouTube Channel).

                                  I found time sooner than I thought to integrate the menu-search function into the main code for this thread’s topic.

                                  Here’s a replacement script; obviously, quite a bit more complicated.
                                  But, due to the virtues of encapsulation, the run() function looks very much like the original, simpler script (the first script provided in this thread).

                                  I call the script CloneActiveDocAndCreateDualPageView.py and here’s its code:

                                  # -*- coding: utf-8 -*-

                                  user32 = ctypes.WinDLL('user32')
                                  
                                  MIIM_STATE = 1

                                    One thing I noticed… In the code you provided, you called:

                                    notepad.getMenuHandle(1)

                                    and it works to get the main-menu handle (I suppose! because the rest of the logic works!).

                                    But the documentation for this says 0 should be the main menu:

                                    507731ce-419d-4953-80dd-f062f40fa196-image.png

                                    Is my PythonScript documentation simply out-of-date in this regard?
                                    Or…?

                                      Not sure if this is an issue with PS code or documentation?
                                      But yes, 1 seems to return the main and 0 the plugin handle.

                                        When I implemented in perl, I used 1 for main and 0 for plugin. The NPPM_GETMENUHANDLE docs agree that 1 is main.

                                        The PS docs are wrong.

                                          When reading a book, you have lelf and right page open thus I was thinking in np++ this book view side by side would be a natural option to have.
