I use Rectangular Patterns almost always in Spacing type rather than Extent. Unfortunately I usually forget to change this before entering directions and distance values, so then I go back and change the Distance Type to Spacing. This is where it gets annoying - when you change the Distance Type it recalculates the distance you have already entered to match the overall dimensions. This makes sense if you've set that distance by dragging the arrows, but I always type the numbers in directly so it means I have to re-enter the number every time. Example - create a rectangular pattern, enter quantity of 5, distance of 100. Change Distance Type to Spacing and the distance resets to 25.
Best option for me would be to have the distance value unaffected if the pattern type is changed. I realise some people may rely on the overall dragged distance remaining the same when you change the pattern type, so it may be too big an ask to request this.
Alternate option: either a way to set a default Rectangular Pattern type (in my case Spacing) or at least have it repeat the pattern type you last chose.
