Entering "Style" in GUI should be easier

[TaygaHoshi]

Currently it's hard and confusing to use the "Style" input.

There could be a scrollable table where you can enter distinct roles:

• Convenient, everything just works
• Easy to understand

• Easy to make a mistake and hard to delete wrong values
• Need to reenter values every time
• Harder to code

Or, style info could be taken as a file:

• Easier to code
• No need to reenter values every time
• Hard to make a mistake and easy to delete wrong values

• Inconvenient, you would need an extra file around
