Looking at the library page, would it maybe be better to have:

1. The search bar fill width
2. The four top buttons will width (to increase touch targets and make it symmetrical)

Otherwise looks good, I can't test how the changes feel on my phone at the moment.

I didn't really touch the gallery view, but that's a good idea yes.
