 ------------ Tyra's v2.0 roadmap to publish on GitHub ------------
+- [General] builder2
+- [General] std::vector in mesh instead of array**
 - [General] Allow to edit all data from mesh/texture
+- [General] manycolor -> lightmap
+
 - [General] USB test
 - [General] Tyra version, render it on start 
 - [Renderer] Fog
@@ -36,6 +40,7 @@ because Mesh rendering uses only core.render()
 - [File] Async file loading
 - [tyrobj] Add multicolor support to tyrobj
 - [Tyrobj] Improve obj importing for multiple usemtl with same names
+- [tyrdata] Custom 3D data file with precalculated bboxes with support of async loading
 - [Renderer] Interlacing
 - [General] Add cpp lint checker in GitHub
 - [General] Control generated id to avoid duplication. Maybe Just increment from 0? Add interface IIdentificable?
