Notepad++: cursor past end of line / virtual spaces?

Sort of a hack (sends a window message directly to the Scintilla edit control on startup), but works great:

1. Install NppExec plugin

2. Go to Plugins -> NppExec -> Execute

3. Enter the following code:

   // ensure console stays hidden
   NPP_CONSOLE 0
   
   // enable virtual spaces (cursor past end of line) outside column edit mode
   SCI_SENDMSG 2596 3 0
   
   // SCI_SENDMSG == send message to Scintilla edit control
   // 2596 == the message we're sending is SCI_SETVIRTUALSPACEOPTIONS
   // 3 == send the value (SCVS_RECTANGULARSELECTION | SCVS_USERACCESSIBLE)
   // the default value is 1 (just SCVS_RECTANGULARSELECTION) for
   //   virtual spaces in column select mode only
   // you can find these values by poking around the source code a bit, or
   // see http://www.scintilla.org/ScintillaDoc.html
   

4. Click the Save button at the bottom, and give the script a name

5. Now go to Plugins -> NppExec -> Advanced Options

6. On the right, under "Execute this script when Notepad++ starts", select the script name you just saved

7. Click OK, close/reopen Notepad++, and enjoy ;)
