GIMP stroke selection should have a thickness preview
Operating System:
All
Description of the feature
When you make a circle or square and you select stroke selection to only draw among the outline, there should be a preview of how thick it will be when the outline is created. This will save many steps when you don't know how thick the outline will be and you want to reduce from possibly 10+ steps because you redid the stroke selection a few times to find the right thickness to just the first time. Not just for the thickness, but also how the color will look when created. The shape creation TODO on the roadmap could be erased potentially if this feature is implemented because it would be redundant.
Use cases
This would be a major convenience in shape creation. Rather than having to do the stroke selection multiple times which can become extremely tedious after a while, you can get it done right the first time if you had a preview of how thick the strike selection was going to be.
