One of quite annoying usability issues is that in many cases min/max values are unknown and/or unpredictable.
Few examples:
- all LPE options
- Gaussian blur - 0 to 100,0 of what - pixels?
A hint for them could include the missing bit of information, e.g. "... (0 to infinity)."
Here, at least these values for gaussian blur are intentional. They could be described as percentage, though it's not too clear, from what that percentage is. (100% here AFAIK is half of the average of object width and height)
It's not supposed to be a precision tool, but to give a visually sensible range of values for any size of object. If you have 5x5 object, 100 corresponds to standard deviation of 2.5 pixels. If you have 500x500 object, 100 gives standard deviation of 250 pixels.
Maybe it should be labeled as "Blur, %"
