From my recent experience, the system process Tracker truly was a pain in the ***.

It ate up to 90% of CPU and consumed battery juice at a pace of 3% per 10 minutes. I had to do a total system cleanup before it turned out normal again.

My question is what's the point of Tracker, except from updating music library and picture gallery?

I understood N9QTweak has this option to add folders to IgnoreList. How can I use this to my advantage? Or is it just a way to hide picture from gallery?

Can I disable Tracker? What are the possible consequences?

Thx in advance.
