A large number of settings in Blender are conceptual percentages. They have a defined minimum and maximum value.
The problem is that these percentage values are not handled uniformly. Some percentage values are represented as sliders, some as regular number fields. Some are represented in values from 0-1 and some are represented as values from 0-100.
Here is a small subset of the percentage fields in Blender:
- Display all percentages uniformly
- Always use sliders for percentages, because it makes the percentage visually clear and comparable
- Use values from 0-100, and show the % symbol to let users know that it is a percentage
I think the main reason for using 0-1 instead of 0-100% is that values are stored as 0.000-1.000 internally? So, the question is, could such a conversion happen at display level?
