Latest IM: If I pull a shortcut to Photoshop from the desktop to a favorites tab it doubles the heights
of all existing favorites in that panel.
If I pull the shortcut into an empty favorites tab it shows as double high.
IMatch uses the height of the application icon. It controls the height of the Favorite. The icon height is typically 48 pixels on modern Windows computers. This is how it works, IMatch does not scale the icons to 16 px like the default icons you can choose from.
This behavior is by design.
But that all other favorite tiles on the same tab also switch to double height as soon as one such is added?
Yes. There is only one height for all Favorites in a group/tab. Else the layout would break.
