Small but annoying bugfix release.
Fixed
- Reader and library settings could silently reset. The one people noticed most was the 3D page-curl toggle turning itself off, but any setting could be affected. The cause: settings were written to disk asynchronously, so if the system killed the app process before that write finished (aggressive battery savers, or right after an update), the change was lost. Now all the on/off and choice settings are saved synchronously, so they stick immediately.
Sliders (font size, margins, spacing, curl speeds) still save asynchronously on purpose, to keep things smooth on large libraries.
No other changes. Safe update over 1.6.0.
