- The [font rendering](https://castle-engine.io/manual_text.php) behaves better when the text contains a character that we cannot render: it displays a fallback glyph (usually “?”) and makes a warning (using `WritelnWarning`, so it goes to [log](https://castle-engine.io/manual_log.php)). This allows to easily spot missing characters in the font and makes backspace working sensibly if you input a character which glyph isn’t supported.

You can toggle this by setting [TTextureFont.FontData.UseFallbackGlyph](https://castle-engine.io/apidoc-unstable/html/CastleTextureFontData.TTextureFontData.html#UseFallbackGlyph) to `false`.

- [TCustomizedFont.Load](https://castle-engine.io/apidoc-unstable/html/CastleFonts.TCustomizedFont.html#Load) allows to load font texture in a couple of alternative sizes. The resulting font rendering will look better, it will use the best texture, and thus can look crisp regardless of the final size on screen.

- [TCastleFloatEdit](https://castle-engine.io/apidoc-unstable/html/CastleControls.TCastleFloatEdit.html) and [TCastleIntegerEdit](https://castle-engine.io/apidoc-unstable/html/CastleControls.TCastleIntegerEdit.html) allow to easily edit a Single / Integer value by an edit box.

- [TCastleScrollViewManual](https://castle-engine.io/apidoc-unstable/html/CastleControls.TCastleScrollViewManual.html) allows to have a scrollbar that controls… well, anything you want (handling [OnChange](https://castle-engine.io/apidoc-unstable/html/CastleControls.TCastleScrollViewManual.html#OnChange) event). This is a more flexible version of [TCastleScrollView](https://castle-engine.io/apidoc-unstable/html/CastleControls.TCastleScrollView.html) that scrolls user interface inside.

The new controls and font rendering capabilities can be of course easily tested in [CGE editor](https://castle-engine.io/manual_editor.php).
