Novelwriter

**Documentation**

* Added documentation in English. The help file opens in the document view pane when the user
presses `F1` or selects it from the Help menu. PR 27.

**Themes**

* Complete rewrite of how syntax highlighting and GUI themes are handled. These are now set
separately, and the dark theme uses QPalette to handle the dark colours, which makes the dark
theme a lot more portable between operating systems. 34 and 35.
* Added the five "Tomorrow" colour themes to list of syntax highlighter themes. PRs 34 and 35.

**User Interface**

* Added a preferences dialog for the program settings. It is no longer necessary to edit the config
file. PR 30.
* The document viewer remembers scroll bar position when pressing `Ctrl+R` on a document already
being viewed. PR 28.
* Removed version number from windows title. PR 28.
* The auto-replace items in Project Settings are now editable. PR 29.
* Changed how document margins are handled. This implementation works better and drops the
difference between horizontal and vertical margins in favour of using the QTextDocument margin
setting. PR 33.

**Code Improvements**

* Spell checking is now handled by a standard class that can be subclassed to support different
spell check tools. This was done because pyenchant is no longer maintained and having a standard
wrapper makes it easier to support other tools. PR 31.

**Bug Fixes**

* Closing the application with the window X button, and selecting No on the dialog, still closed
the application. Properly handling the close event now so that the closing is cancelled. PR 21.
* Many of the menu option would cause novelWriter to exit or otherwise make mistakes when clicked
if no project was open. They all check for this now. PR 23.

**Timeline**

* Added an index to the project that holds the position of all headers in the novel part of the
project and all tags set in the notes part. It also holds all the links from novel files to
notes. The relationship can be viewed in a new TimeLineView GUI. It's in the tools menu, and can
also be opened with `Ctrl+T`. PR 22.
* The spell checker now used this index to highlight keywords/value sets. If the keyword or value
is not valid, it will not be highlighted and will instead have a wiggly line under it. This also
checks that references point to valid tags. For this to work, the index has to be up to date. The
index of a file is saved when the file is saved, but the entire index can be rebuilt by pressing
`F9`. PR 22.

**Status Bar**

* Redesign of the status bar adding project and session stats as well as a session timer. PR 21.
* Project word count is written to the project file, which is needed for the session word count.
PR 21.
* Closing a project now clears the status bar. PR 21.

**Editor**

* Spell checker now ignores lines staring with ``, and words in all uppercase. PR 21.
* A document can be closed, which also clears it from last edited document setting in the project
file. I.e. it is not re-opened on next start. PR 21.
* Tab width is now by default 40 pixels, and can be set in the config. PR 21.

**Bug Fixes**

* Fixed a bug where an item had to be selected in the tree view for a root item to be created.
PR 16.

**User Interface**

* The main area can now be split into two, with the document editor on the left and a document
viewer on the right. PR 13.
* The list of novel document status and plot element importance levels can now be edited through
the Project Settings dialog. The values are per project, and saved in the main project XML file.
PR 17.
* Cleaned up opening and closing projects, as well as how new projects are created. A new project
can also not be saved in a folder already containing a novelWriter project. That was previously
possible, resulting in the old XML file being overwritten. PR 18.
* Some minor GUI improvements were added, PR 19:
* Pressing `F2` also opens the edit item dialog, like `Ctrl+E` does.
* When the document editor and viewer split slider is moved, the editor resizes properly.
* The document viewer can be closed, expanding the editor to the full window size again.
* A project can be closed with `Ctrl+Shift+W`, and the menu entry has an icon.
* Exit button/menu now asks if you want to close.

**Themes**

* The colours for syntax highlighting can now be edited in a config file in the themes folder. The
main GUI css file also lives in the same folder. The default theme lives in the default
subfolder, and more folders can be added. Switching themes involve changing the theme setting in
the main config file to the name of the themes subfolder. PR 15.

**Code Improvements**

* Loading the project with the items in the wrong order is possible. That is, the child item is
stored before its parent. A saved file should not ever be like that, but an edited file might.
Even if the file shouldn't be edited manually. PR 16.

----

**User Interface**

* The cursor position is now saved when a document is saved, and restored when the document is
opened. PR 12.

**Test Suite**

* Major upgrades to the test suite, now also testing GUI elements. Coverage at 73%. PRs 9 and 11.

----

**Bugfixes**

* Fixed a critical GUI bug when trying to create new folders and files in the tree.
* Caught a bug when creating a new file, but novelWriter couldn't figure out what class the parent
item had and returned a `None`. Could not recreate the bug, but added a check for it anyway.

**Code Improvements**

* Changed the way user alerts are generated, and added the alert levels to an enum class named
`nwAlert`. Also added a new level named `BUG`.

----

**User Interface**

* Rewritten the spell check context menu. The previous implementation was adapted from a Qt4
example, but could be improved a great deal. It now also doesn't have the default context menu,
and allows for adding words to personal word list. Spell checking can also be enabled and
disabled from the menu, and re-run on a the current document. PRs 1 and 3

**Test Suite**

* Added a unit test framework based on `pytest`. This currently checks basic opening and saving of
the main config file and the main project file. PR 2
