@iudqnolq Thanks for your suggestion!

A few problems (padding of those virtual book cover) I have already tried to fix before posting the "SHOW HN" thread. But you have given me a lot of other clue to improve.

Yes, I'm using material design, but at a superficial level, after the initial releasing, I will spend more time at better use the design tool. (eg: lever up color).

The "storage" button is just an entrance of popping up menus. I will change it in the next release version.

Your modest but inspiriting language gives me lots of engergies. Thanks again.
