"MoveHalf" and "ResizeHalf" attributes for resizable dialogs

[Snowman]

I was pleased to see that making resizable dialogs with Pelles C is very easy: include resizer.h, link resizer.lib then add the attributes for "Vert resizing" and "Horz resizing" in the resource's dialog editor. So far so good.

The problem is that there are only 3 possible attributes: None, Resize and Move.

I would like there to also be attributes such as ResizeHalf and MoveHalf. These could have the effect of resizing or moving proportionally, specifically by half.

Now a bit off topic: I have noticed that there isn't much forum activity from Pelle so, assuming he won't read this Feature Request any time soon, I'd like to know where the source code for the resizer library is, thank you.

Installer put it in user's home dir to dir 'Pelles C Projects' ?

I am curious: Can you post a working example of such a dialog?

I have been experimenting with this idea, not in C, though - is the attached example more or less performing what you want to achieve?

GuiMenu equ @File, &Open, &Save, -, E&xit, @Edit, Undo, Copy, Paste
include \masm32\MasmBasic\Res\MbGui.asm

; attributes x, y, w and h expressed as 1/1000 of width resp height
GuiControl Ctrl1, "edit", w 400, h 200, text "first edit"
GuiControl Ctrl2, "edit", x 400, w 400, h 400, text "second edit"
GuiControl Ctrl3, "edit", x 800, w 200, h 600, text "third edit"
GuiControl Ctrl4, "static", y 200, w 400, h 800, text "static"
GuiControl Ctrl5, "listbox", x 400, y 400, w 400, h 600, text "listbox"
GuiControl Ctrl6, "button", x 1000-80, y 1000-30, w 0+80, h 0+30, text "button"      ; fixed size button

Interesting. So the { args } tell the resource compiler that these elements are resizable?

I saw an example by malxau here, but he uses a different syntax:
LISTBOX 4,                               5, 85,  130, 60, WS_TABSTOP
DIALOGRESIZECONTROL { 0, 100, 0, 0 }
