I've made a phi-connect system to manage arduino wires. It easily helps you switch between several projects without having to disconnect and reconnect tons of wires, saving you so much time.
Here is a picture:
Here is a video:
I have two projects on one board and I switched between the two project in seconds.
I wish I had this a while ago so I didn't have to
when I took my arduino out of this project. With phi-connect, I can take out the arduino and put it back in within a few second, no memorization of which wire goes where.
You can also use this system to tidy your breadboard and arduino, ridding the crazy jumper wires. Plus if you use it in finished projects, you can remove your arduino and return it any time you want, all with ease.
