Conditional formatting gets bogged down when you have lots (I have a few hundred on a single form) and it can take a minute or more (60+ seconds) to bring up the conditional formatting screen when there are that many and then take another 60+ seconds to update each conditional format. This makes it very difficult to make any changes when you have this many as well as being difficult to add new ones and manage what ones you have.
It would be great if there was a way to load the specific conditional information in a file so that they can be managed and easily changed outside the interface.
