Padding controls are not working as expected. It seems that this property has been broken during last release versions.
I have an item menu in my setup with dimensions = width 45 x height 58
If I set "Padding Top" to 0, the icon is shown in the middle of the floating menu.
If I set "Padding Top" to 1, the icon is shown in the bottom of the floating menu.
If I set "Padding Top" to 30, the icon is shown in the bottom of the floating menu.
So there is no difference between 1 and 30, the result is the same.
Could you maybe copy & paste the item where 1 and 30 result in the same? Is maybe the height of the item just set to a high value? Maybe try setting to "fit content" instead
there was a recent bugfix for padding that might cause this. Previously there was always some padding added implicitly and there was no way to disable that. Now if the padding is set to 0, it should really be zero. I'll check whether I can reenable this old behavior for items that have been created with previous BTT versions!
