+Miscellaneous
+-------------
+- Use VertexArrays/VertexBufferObjects/DisplayLists/etc
+- Plugins can time/location references too a tree-view
+
+GisObject:
+  - Improve GisMarker
+  - Add min/max LOD
+  mabye: ?
+    - Add linked list node to GisObject for add/remove
+    - Move rendering code to objects intead of GisOpenGL
+       - How to work with non-opengl renders, do we care?
+
+GisTile:
+  - Prioritize tile updates
+  - Only updates visible tiles
+  - Render correct tile resolution when zooming out
+  - Integrate with GisTile?
+  how:
+    - Update tiles after each render
+    - Use backfaces to only fetch rendered triangles for each tile
+    - Only split/update/load tiles that are used
+
+Roam:
+  - Find a better way to fix great circle errors
+  - Improve garbage collection (use timeout?)
+  - Refactor height functions
+  - Fix texture rendering at edges w/ linear filtering
+
+Improve plugins
+---------------
+env:
+       - Config panel
+  - Add atmosphere, sun, etc
+
+elev:
+       - Config panel
+       - Runtime option to draw heights
+
+sat:
+       - Config panel
+
+map:
+       - Config panel
+  - Use local rendering instead of pixmaps
+
+gps:
+  - Create/test it
+  - Config: follow position, draw trace, leave marker
