Namely, don't recompute layouts, as they do not change.
(The gyro codepaths were already doing something similar.)
* Keep ConfigDialog, FileManagerMenu & ReaderMenu open on rotation.
(In practice, only ConfigDialog is affected, as *Menu doesn't handle the rotation event.)
* Plugged an instance leak in the aforementioned Menu classes.
* Unify behavior & code with the gyro codepaths.
These changes make the title bar in File manager, History and Collection windows of the same height.
The items and book covers thumbnail dimensions in Mosaic and Detailed list display modes are now equal, and up/down scaling of the thumbnails is not needed when switching between File manager, History and Collection.
Maintain correct records in History and Favorites when moving/deleting folders or group of files.
Optimize Collection module to minimize storage requests.
* New menu option and filemanager filter to hide finished books #7158
The default behavior is to display the finished books (no change on
upgrade). For consistency with the two similar options, it represented
by a checkbox "Show hidden books" that is checked by default.
The implementation is straightforward, meaning that, when the option is
unchecked, each file will require a call to `filemanagerutil.getStatus`
that checks its status.
For clarity, the code uses the "finished books" expression because the
condition is relevant to the *book* metadata, while the other settings
are about *file* attributes.
The Kindle swipe animations & physical key inversion apply *everywhere*,
so we need this accessible in the FM, too.
Move it to Navigation, which is where it already was on !Touch devices.
Export highlights for selected files.
Having a button "Select all files in folder", it is easy to export the whole folder.
So, closes#10402.
To keep even number of buttons, added a feature "Show selected files list". May be useful to check selections before an operation. Just a sorted list, no titlebar or popup menu, tapping a file jumps to its folder.
