I am currently designing a CNC mill 
The problem I have sometimes is to find a component or feature. Very often is it a joint or motion link I am looking for.
The project has now been refactored several times to take certain situations into account.
Result is that I do rigidly give names to each entry in the browser and also categorize hefty to find stuff by pure logic.
My problem is still, sometimes drops the performance in Fusion drastically if many joints or components from McMaster-Carr are inserted.
Try 100 bolts and place them with joints 😉
So the trick is to turn of "Capture History" at convenient points and turn it on again.
This is also a kind of brute-force cleanup as bad placed joints and similar simply are deleted.
I have spent 4 hours trying to find a joint which didn't exist 😞
I would love a search tool box above the browser. So when you e.g. enter "link" in it every entity with the name or according property "link" gets filtered out and displayed solely.
