Here's something I do occasionally. One of my colleagues was having trouble with one of his models just now and I was able to sort it using this technique. Not seen it described so in case it helps anybody:

Problem: I've got a feature I need to re-order but I can't because it's a child of an earlier one. It may not be readily apparent exactly what is causing the parent/child relationship. If I suppress the parent to attend to the child, the child is suppressed as well, so I can't change how it relates to the model. My detail drawings are done, all showing the driving dimensions, nicely laid out, so deleting stuff may well cause a lot of work.

Solution adopted: I find the parent feature that's causing the problem, edit its sketch and change one or more of the lines or arcs to construction lines. The feature then intentionally falls over when I force it to rebuild, and the software does its best to rebuild the model without it. I now edit the child sketch and remove any dangling constraints or dimensions. (These are now highlighted and can easily be identified). Add some new ones as necessary and rebuild. (Or perhaps edit the feature to change the sketch plane or whatever). Because the original parent is temporarily non-existent, the child cannot now have the same parent and can be re-ordered before it. Now edit the old parent sketch, change the construction line back to full and rebuild. Minimum loss and upset of the detail drawings.

It's particularly useful if there's loads of configs and detail drawings of same.
