Well it sounds like the smaller cache size is what you're looking for.
My feeling around this feature is I would offer it only on jelly bean and up. A new permission is available to only access the application directory and nothing else but on all SD cards, not just the internal storage. This would prevent listen up from seeing things like pictures, etc., I don't like it when other applications do that but before jelly bean, it was necessary for me to do it. This would allow me:
- Access the SD cards with an eye on removing the "full" SD card permission that allows listen up to see everything on the SD cards.
- Keep in mind i consider listen up idle ware at this point. I haven't made a release in over a year, so don't hold your breath.
I would like to make a new maintenance release soon, but it's exactly that, maintenance, it fixes the 3-4 bugs that have been reported in the last year.
