Allow for embedding "tags" (invalid Unicode codepoints)
in the text string to trigger some text formatting:
for now only bolding some parts of text is possible.
Use it with fulltext search "all results" to highlight the
matched word (instead of the previously used brackets).
People using 2-steps text selection (via the Select button) may
want to not be annoyed by this feature.
Also tweak a bit its behaviour, requiring now the text selection
to come from outside a corder into a corner to activate it, which
should allow starting text selection from a corner without
triggering a scroll yet.
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.
Just prevent page thumbnails ImageWidgets to be nightmode
inverted, unlike all other ones which are expected to be
double inverted to get their original colors shown.
The same thumbnail can be used and cached in both day and
night modes, unless "nightmode_images" is enabled and have
crengine itself invert images, making thumbnails different.
Checkboxes under TOC>Settings> allow enabling Custom TOC
and Custom hidden flows (similar to "Hide non-linear fragments"
available with some EPUBs).
Handled by a new ReaderHandmade module.
Adding and removing TOC chapters is done in PageBrowser
with long-press on a page thumbnail, and for chapters also
in the popup dialog after selecting some text in a page.
ReaderToc: add a symbol in title when the TOC is the
alternative TOC or the custom TOC.
When enabled in BookMap, both BookMap and PageBrowser get:
- alternating gray background on chapter spans
- hatched background instead of uni-gray on hidden flows.
Also, with both normal look and this alternative theme,
show some hatched overlay on thumbnails part of hidden flows.
ReaderToc: for each TOC item, have it carry its sequence/number
in that level (we do this in validateAndFixToc() where we are
already iterating all the items).
If originally with two-columns in page mode, and switching
to scroll mode, thumbnails generation would be slow as
the document would be rerendered for each thumbnail.
