I've noticed Samsung widgets can be inconsistent in regards to the settings options and look. For example, the calendar monthly widget has a blurred background but the reminders widget has a transparent background instead. I think a blur switch option should be given to all the widgets just like there's a background switch option. Also, the old transparency slider was better since it gave more control as opposed to just 3 presets. As another example, the galaxy buds widget still has the old slider with no background switch option and no blur. So basically, return the old transparency slider which makes the background switch unnecessary and replace that with a blur option.
