No, it looks like this:
| root
| –bone1
| —slot1
| –bone2
| —slot2
<...>
| –bone x
| —slot x
Then I definetly selected image, cause the next slot moves under the new bone automatically:
| –bone x+2 (After creating this bone all next bones get name "slot+1", even after renaming this bone.)
| —slot x+1
Bone x+1 is not exist at all, so I need to manually rename the "bone x+2" to descrease the number.
Sorry that I can not share screenshots.
