One feature that I am missing that UltraMon has.

I would like to see window scaling when a window is moved between monitors of differing resolutions. The window is resized so that its proportions remain the same. Right now if you move a window from smaller resolution to larger resolution, the window size stays the same. I would like an option to upsize (or downsize as required) the window size so that its proportion remains the same.

I think this can be done with hot key macros, though you'll have to play with it: see attached... I think this came up before so maybe someone will hop in with an example...

Thanks, the proportion option handles hot ketys but that still leaves a need.

When I drag a window across monitors, I need for it to proportionally resize. Example, dragging a window larger than the destination monitor, as the window comes onto the monitor, it need to display proportionally so that it isn't exceeding the size of the monitor.

Please read my second message again. This relates to dragging a window, not a hot key. This is functionality that UltraMon has. Sometimes I wish to use the mouse to position windows and they don't resize proportionally when moved to another monitor in this manner.
