Ok, If I Hide a folder in QuickPic it does write a no media file to the folder. So then the folder doesn't show up in your Media /Images folder. But I can see the hidden folder & it's contents if I explore ths SD card folder system. I also found how to view hidden system files like the actual .nomedia files, under "View" ....
My apologies, as some things are as you intended. We just need to find.or learn them.
I can't seem to make the icons & text view in list view of the Media Images folder access smaller yet? It only seems to make thumbs smaller on grid or gallery view where there is no text. I'll keep playing.
