Existing tilemap tiles are rigid realizations with:

• lack of basic features ( color, transform, sprite manipulations ) which are allowed by TileData / AnimatedTileData
• feature set of any Tile is fixed, no customization / optional modules, that have to add repeatatively byself
• lack of Inspector Undo
• Replace Tile type is big issue (change from RuleTile to TerrainTile etc )
• lack of Copy / Paste
• Rigid custom Inspectors, disallowing use Odin, or built-in Range / Header / Space Attributes for Inspector customization

• SerializeReference to have optional modules
• no use custom Inspector / PropertyDrawers , to allow Odin, save built-in Undo, Copy / Paste, etc

1. Demo Scene, tiles, extensions
2. unitypackage to direct import
3. full source code on Github to explore
4. if your project contains Odin Inspector - ExpandableTile will use it, if not
5. TypeToLabelAttribute and custom ContextMenu to comfortable usage

• ExtendableTile - CustomTile, that aggregates TileExtensions
• TileExtensionSO - ScriptableObject, containing TileExtension, can be referenced from ScriptableObjectEx

1. AnimateSpriteEx - analogue to Animated Tile
2. WeightRandomSpriteEx - analogue to Weight Random Tile
3. TerrainEx analogue to Terrain Tile
4. PipelineTileEx - analogue to Pipeline Tile
5. ColorOutlineEx - evaluate Gradeint based on same-tile-neibhours-count, smooth sides
6. PositionMapEx - Remap tile position with split random MinMaxCurves for X and Y
7. RandomColorEx - Multiply tile color to MinMaxGradient.Evalute(), has Perlin module
8. RotateMapEx - Remap tile rotation with random MinMaxCurve for Z
9. ScaleMapEx - Remap tile localScale with random MinMaxCurve for XYZ
10. ScriptableObjectEx - refers to TileExtensionSO and execute it's TileExtension

• Project Window -> RMB -> Create/2D/Tiles/Extendable Tile / Extension

• TileExtension property title -> RMB -> set to [Extension]

• Unity 2020.2 Array became reordable at this version

• #3 some TileExtensions need Enter / Exit PlayMode to Refresh
• #4 at this moment position rerandomized after any changes in any listed ExtendableTile.Extensions
• #5 ⛔ Error log 'Use RegisterCompleteObjectUndo' - not braking anything
  
• #6 ⛔ MinMaxGradient dropdown almost not clickable - problem in Unity own realization, if you use Odin - it works fine, either you write own CustomPropertyDrawer, or you can switch Inspector to Debug mode, and switch gradient-type there

• #3 RefreshTile() Implementation
• #4 Seed-based Randomization
• #2 SiblingRuleEx (Existing Rule Tile has rigid Inspector, i've ported it to PropertyDrawer for RuleEx, but it's not ready-to-use)
