Sticker bottoms - Subfile or Primitive

[Philippe Hurbain]

A couple of thoughts:
- I think subparts are a better location for these. Yes, I know about the documentation question but nothing is stopping us from have the same proposed naming convention.
- Regardless of the above, formed backs should always be subparts. The primitive folder should be kept as clean a possible and I don't want a bunch of obsolete prims because the part number changed.
- IRL all stickers have rounded corner but corners should only be modeled rounded if the rounding is more that the default.

I agree with Orion (especially the last point!)
