I do something similar. My favorite thing about it is that it allows me to keep momentum. When I start to get bored of whatever I'm currently working on, I can open up my ideas file and daydream about the next thing. Having something else to look forward to is very motivating for me. It both makes it more likely that I'll finish my current project, and prevents me (most of the time) from falling into a rut where I don't know what to do next.
