o Geometry instancing (CLIENT)
  - Pseudo instanced cylinders.
  - ANGLE_instanced_arrays perfect-/points-spheres, then cylinders.

o Multiple bonds from CIF dictionaries (CLIENT ONLY)
  - From data island.
  - From local dictionary file.
  - From EBI/PDB?
  - From local monomer library?

o Multiple lights. (CLIENT)

o Atom selections (CLIENT ONLY)

o Colouring schemes (CLIENT ONLY)

o BUGS
  - This does not work in MapDisp in scene.xml: <style>surface_style_chickenwire</style><surface_style>surface_style_solid</surface_style>

o Symmetry (SERVER/CLIENT, CLIENT)

o Save current scene to view in CCP4MG

o Primitives (CLIENT)
  * Latex/MathML text, which looks a bit difficult.

o Menus on GUI show something. (GUI)

o Full Display Table
  - Other display objects: surfaces, h-bonds, maps, annotations, etc.
  - Selection browser tools: Logic, interactive selection (requires line widths).
  - Metal on simple menu.
  - Edit transparency.

o Wizard choices.

o More atoms to triangles in client.
  - Thermal ellipsoids:      Atoms + B/U -> spheroids.
  - Hydrogen bonds:          Atoms + HBond calc -> lines
  - Contacts:                Atoms + contacts calc -> lines.
  - Worms scaled by b/nmr:   Atoms (+B) -> CAs -> spline -> worm.
  - Nucleic base blacks:     Atoms -> rna/dna rings -> triangles.
  - Bloboids:                Atoms -> bloboids.
  - Circles:                 Atoms -> circles.
  - Perfect spheres:         Atoms -> perfect spheres.
  - Base pair sticks:        Atoms -> HBonded base pairs -> cylinders. (HARD, want H-Bonds.)
  - Lipid cartoon:           Atoms -> lipids: tail -> spline -> worm  -> spheroid; head -> spheroid. (HARD)
  - Glycoblocks:             Atoms -> sugar rings -> glycoblocks. (HARD? Might be better way than in MG)
  - Surface:                 Atoms -> surface (HARD, might be able to obtain code/algorithm).

  - Require:
      * maths: eigensolver, svd(?) Could/should use numeric.js.
      * primitives: spheroid, perfect sphere (might not be possible).

  - Colouring:
      * By chain
      * By entity
      * By model
      * Main/side
      * Rainbow
      * Residue type
      * ASA
      * Hydrophobicity
      * B-factor
      * Browser

o Statefulness: ??? (The elephant in the room)
  - Local storage - thsi might be best. (CLIENT)
  - Keep process alive on server. (SERVER):
     * Remove QApplication mainloop requirement of MG so that it can be run in non-main thread. This
       is potentially very tricky.

o Only click on atoms not fogged or clipped. (CLIENT)

o FPS (CLIENT)

o Simple Display Table (CLIENT)

o Stereo/3-way (CLIENT)

o Rock/roll (CLIENT)

o Scale (CLIENT)

o Render/screenshot (CLIENT, in progress)

o Generate helices (CLIENT)

o Applications where we should use web services if possible:
  - Superpose
  - Download SF, maps, PDB_REDO, etc. 
  - Ebeye
  - Get monomer
  - PISA

o Sequence viewer

o Harder/unknown applications:
   - Normal modes (Simple calc in JS, if we have an eigen solver).
   - Get smiles ???
   - ProSMART ???
