Hello!

Very nice program here! I was using Sizer for years but this is a lot better!
I just miss one feature, if I can suggest it to you...

What I would like
I LOVE how I can add my custom windowSizeItems in the XML with associated shortcut keys. I would like to do the same with screen locations without resizing the window!

What I tried
I tried to add an item line with left and top to a custom value and leaving width and height blank, but this prevents the program to launch (with an error).

What I hope we can do
One of these three:

• Allow a windowSizeItems item to have top and left values without width and height specified.
• Add an item like align_top_left but with top and left attributes.
• Add a windowLocationItems, similar to windowSizeItems, with a list of custom locations. [preferred]

Further ideas
In case of a windowLocationItems section, top and left values could also use const values like screen_width, screen_top, etc.
And why not small calc possibilites, for example (screen_width - 32) / 2.

Thank you for your hard work! Wish you the best,
Léo
