I have a similar mind map that keeps reference to the organization of it all from the topmost level. Since it is higher up in the chain, I refer to it only during monthly or less often reviews, and only then in a framework of "quality of life" decisions. Otherwise, I prefer using a Kanban-type chart as reference during daily / weekly reviews ...

I have also found a very helpful habit is to set clearly circumscribed review increments on projects, followed by almost religious daily and weekly review routines. Daily reviews are set on my projects that are ongoing NOW and may have immediate changes on a daily basis. Practical examples are actions lumped generally in each folder as "Chores". Weekly reviews are set on projects that are more stable yet could have gross developments in that time. The renovation project at my father's house is an example. In an emergency though, even certain parts of weekly projects can get pulled out to a daily review schedule. Monthly steps even further in project stability and happens especially for On Hold projects. Finally, the yearly review is set on my Vision statements for each Area of Responsibility (folder).
Daily ... I open my Kanban(s), open OF in Review mode, and track only what might need to be changed (create, delete, modify tasks) on each project before stamping it Mark Reviewed. Then, I go about activating my work schedule for that day (by flagging tasks). Weekly, I summarize and store the Kanban(s), and then strip them down and reorganize to start over for the coming week. I correspondingly open OF and reorient the project schedules, times, and task layouts accordingly.
I admit, it can at times seem like a lot of work. Even I would sometimes rather go play on the Web than tackle the work schedule issues (let alone tackling the actual work load). So some slippage happens. But then, having a framework that, when I put my mind to it, really does GET THINGS DONE keeps the perspective honest and the effort worthwhile.
Seems like you've got a good start yourself ... hope this gives some additional insights.
