I like the simplicity of it...
Maybe a brief description... "Changing these values will adjust the Widgets location/placement on your desktop" ??
and "Updates may reset settings to default, you will need to adjust accordingly"
Thoughts of a default button or a note defaults are xx xx - should they want to start over or set back....
Additionally .... and just a thought
And this maybe just me - but I have tweaked the size of mine on some lower res laptops.. *its been a while...
Perhaps the X/Y for those? Just a thought as those would be minimal steps, else wording could run off..
