-- [ ] Texture loading
-- [ ] Model loading
 - [ ] Base Renderer class
 - [ ] Base Physics class
-- [ ] Base Node class
+- [ ] Figure out how scenes should be handled
-- [ ] Base UI Node class
+- [ ] Split other sections into seperate modules (renderers, physics)
-- [ ] Base Audio Playback Node class
+- [ ] Application class (where the main loop is handled)
-- [ ] Split other sections into seperate libraries (renderers, physics)
+### 2D/3D
-## Audio
+- [ ] Texture loading
+- [ ] Model loading
+## Audio Module
+### Base
 - [ ] OGG and WAV support (do first)
-- [ ] MP3 (later)
+- [ ] Soundfont and Midi support (ideal)
-- [ ] Audio playing nodes
+- [ ] MP3 (later, can just ignore)
-## Hibis UI (NEED A NAME)
+- [ ] Loop audio (with timepoints)
+- [ ] Modify sound/pitch of outputted audio
+### 2D/3D
+- [ ] Position-based audio
+## Hibis UI (NEEDS A NAME)
 - [ ] GUI creation
-- [ ] Text Object (rendering via SDL2_TTF (RSDL) or FreeType2 (EVERYTHING ELSE))
+- [ ] Text Object (rendering via FreeType2)

-## RVK (2D AND 3D, NEEDS A NAME)
-- [ ] Window creation (either using GLFW or a custom window creator)
-- [ ] Basic deferred renderer
 - [ ] Render present
 - [ ] Clear renderer
+- [ ] Figure out how the renderer should even work
+- [ ] (DO FOR A VERY LATE VERSION) Replace GLFW with a custom window creator to reduce bloat (I will not be using most of GLFW's shit)

 ## Hibis Physics (NEED A NAME)
+### Base
 - [ ] Physics Shape creation
+- [ ] Option to *allow* for Physics Shapes to be able to be drawn (on by default, both compile time and run time, turn off at compile time via a flag (`-DNoPhysShapeDraw=1`?)) (official releases will include PhysShapeDraw capabilities)
+### 2D/3D
