It's a simple one this time. Custom labels.
Today we were having some issues with a huge project (and I mean "400meg project file" huge). There were literally hundreds upon hundreds of groups, probably half of Southern England was in this file. I noticed just how tidy everything was for a project this size. Everything was very tidily parented to nulls which we often treat as folders and a lot of things were labeled which, in a file this size, is absolutely essential.
So, if you don't already, I suggest labelling everything in large projects, a great bonus is that you can customise your labels, so why not get a scheme going, get used to it and keep using it. It will save you TONES of time.
More on Saturday!
