From the source code, there are different "default" positions:
If nothing is specified within the .ini-file (section [Window]) on NP3 window creation time, the Windows API value CW_USEDEFAULT is used to get a "default" window position from the operating system assiged.
On the other hand Notepad3 has internal default positions :
Notepad3.exe /PD == (Ctrl+Shift+P)Hi @RaiKoHoff,
I think you misunderstood me? 馃
I thought that the size of the Notepad3 window after a new installation (Out-of-the-box) would be at least as the same size as the RESET size proposed by Snap to Default Position (Ctrl+Shift+P) ? 馃槒
Please test development beta "_develop_3.18.503.1011".
Initial default should be same as /PD = /PS = Ctrl+Shift+P

I am guess a new feature born from this Feature-request/Issue-Ticket is causing my problem...
All of my newly opened windows go to a specific window size and shape that IS NOT what I have set in the ini file for the optimal starting size I recorded years ago...
present in builds
Notepad 3 (v3.18.503.1012)(Portable)(DevBuild)(x64) was using when I noticed it...
Notepad 3 (v3.18.503.1013)(Portable)(DevBuild)(x64) as well
so Idk why this is happening... :-(

Sorry, :disappointed:
Please test development beta "_develop_3.18.504.1014".

Hello @RaiKoHoff ,
Much better, the new "NP3 windows settings" and the new affectation of "F11" / "Ctrl+F11. 馃憤
Now, two NP3 windows side by side can perfectly occupy a full screen. 馃槂
