hikidashi app for iPhone and iPad

This is an app that can be classified many photos into several drawers with SAKUSAKU (means smoothly and enjoyably in Japanese).
From the first, I released "Maskingtape" app (the app to decorate a photo with masking tapes), and I was designing a function to classify many tapes into drawers.
I found a enjoyable design, but a little unique.
So, I think to release only this function first, and ask users about its usability.
Please send us impressions or opinions from review board
or twitter (my twitter account is @app_masuo)!
And, if you enjoy this, please try my released other apps!
