 == Open issues ==
-* Change anti-collapse background noise estimator?
-* Reduce waste when splitting at high bit-rate?
-* Stop computing log2Amp() on uninitialized data
-* Stereo/mono switching (Greg's patch and more)
-* Digital silence
-* Check dynamic range
-== Tuning ==
-* Temporal masking
-* 3-tap prefilter/postfilter
-* qtheta offset
-* Just in case (probably not needed)
-** delta allocation for non-transient
-** fine offset
-** Spreading/folding parameter
-** Band layout (spacing)
-== Still possible, but probably not a good idea ==
-* Enable new layout with more HF bands
-* Remove 2-phase stereo?
-* Revert N=1 allocation special case?
-* Revisit folding
-** Can we remove the need to fold on split?
-** Should we do L/R folding?
-** Should we fold the side (probably not)?
-** Band-aligned folding?
 == Post-freeze ==
-* Samplerate switching
+* VBR waste prevention
+* More intelligent VBR decisions
 * Denorm prevention
+* Ogg mapping (including >2ch; LM/ch switching)
