Preferences: added "Capitalize texture names" option (located in Preferences -> Appearance -> Additional options). When disabled, the casing of displayed texture names will match filenames for textures loaded form TEXTURES or pk3/pk7/folder resources.
Textures Browser: added support for displaying long texture names.
Errors list is now cleared when reloading resources.
Visual mode: added basic support for sector slopes (no UI for that feature yet).
Changed "Raise Floor by 8 mp" and "Lower Floor by 8 mp" default shortcuts to "Ctrl-Alt-ScrollUp/ScrollDown", because they used the same keys as "Increase Brightness" and "Decrease Brightness" actions.
Snippets: changed token syntax from $XX to [XX]
[LB] (Line Break) marker can now be used in snippets.
Game Configurations: added "enabledbydefault" parameter. When set to true, a game configuration will be available by default (e.g. when an user starts the editor for the first time).
GZDB will no longer throw an exception when trying to update default value in a TypeHandler, which doesn't implement default value handling.
Script Editor: added snippets to auto-complete list (currently they aren't inserted properly though...).
Script Editor: auto-indentation now works a bit smarter.
ScintillaControl.GetLine() was retrieving incorrect line.
Randomize mode: randomized pitch, roll and scale can now be applied to things.
Randomize mode: removed "Relative" option, because results with this option enabled were almost the same as without it.
Classic modes, model rendering: selected models are now rendered using highlight color, so they no longer blend with thing rectangle/circle.
Model rendering, UDMF: scale was applied incorrectly to models with pitch or roll.
Updated documentation.
Thing Edit form, UDMF: default value of pitch and roll angle controls is now up.
Angle control: direction line is not displayed when showing mixed values.
Thing Edit Form, UDMF: added controls for setting pitch, roll, scale, render style, fill color, alpha, health and score.
Visual mode, UDMF: UDMF scale is now applied when rendering sprites.
Added Thing Statistics form (Edit -> View Thing Types...), which shows all loaded thing types with some additional info.
Visual mode: sprites with negative ScaleX and positive ScaleY were not rendered properly.
Classic modes: display was not updated after loading a sprite.
Current testing engine change was not saved on closing the program when no other game configuration settings were changed.
Moved "Rotate Clockwise" and "Rotate Counterclockwise" actions to "Edit" category.
Tag Statistics form: help label was incorrectly aligned.
Some actions in Sectors and Linedefs modes were not used on highlighted map elements.
Some actions in Sectors and Linedefs modes created undo groups incorrectly when used on highlighted map elements.
"Preferences -> Editing -> When splitting a linedef" setting is now always used when splitting linedefs.
"Preferences -> Editing -> When splitting a linedef": added "Reset X and Y" option.
"Preferences -> Editing -> Auto-align textures of newly created linedefs" option now works in a more intelligent fashion.
GLDEFS parser: added a warning when the interval of animated dynamic light is 0.
Visual mode: fixed a crash when an angle of animated dynamic light was set to 0 and light animation was enabled.
Tag explorer: removed unnecessary mode switching when selecting map elements of the same type.
Make Door action: door and track textures are now stored while the editor is running.
Edit Selection Mode: pasted geometry was not merged with the rest of the map if the selection was not modified before applying the mode.
Make Door action: made Make Door form a bit smaller.
Make Door action: sector highlight was not updated after performing the action when a single sector was selected.
Error Checker mode: added "Check missing flats" check.
Error Checker mode: fixed several descriptions.
Sprite patches for sprites defined in TEXTURES are now loaded from Sprites namespace.
Some of my older texture alignment code didn't work properly when strict texture/flat handling ("mixtextureflats" game configuration flag set to false) was enabled.
Fixed some incorrect checks for missing texture ("-").
