1. Non-Kindle-specific `hasFiveWay` behavior is changed to `hasDPad and useDPadAsActionKeys`. For now they remain Kindle-specific in practice, unless one sets `useDPadAsActionKeys = yes` in a user patch.
2. With that disambiguation out of the way, `hasFiveWay` itself is further disambiguated into `hasScreenKB` and `hasSymKey`, as per the actual property being used, rather than something that tends to correlate with it. (It needn't be Kindle-specific per se, but non-Kindle devices have equivalent shortcuts with for example `Shift`.)
Running the emulator with `DISABLE_TOUCH=1` will set `hasSymKey = yes`, which can be tested with right shift.
Closes#11887.
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.
