Hi I´m new to this forum and pretty new to octane.
I found this thread and thought I´d also share my suggestions.
@ convergen:
Thanks for posting this. Most of the tips were on my list too!
Here´s what mine Looks like. Its Priority based. Most important on the top.
-- Standart mapping types, non UV (Spherical, Cylindric, Cubic etc.) with Scale, Rotate and Move / Position options
-- Output of Images in different bit depths (8bpc, 16bpc, 32bpc) and in different file formats (tif, targa, exr, hdr)
-- Material goes back to "full" Circle after deleting Node (Is there a workaround?)
-- Invert option for bump channel (Sorry figured out that it already exists

)
-- DOF control / Bokeh control such as (Aperture Blades, Center Bias, Anisotropy)
-- In environment option for Independent Lighting/Reflection/Refraction
-- Being able to hide Objects from camera (visibility), gi, reflection, refraction etc. independently
-- Delete nodes with DEL or Backspace key
-- Being able to render layers (depth, material and object buffer, reflection, refraction, shadow)
-- Anisotropy material
-- Dispersion option in refraction
-- Slow mode (to be able to let it run as a background process if you only have one card)
I post this mostly to confirm that most of the suggestions convergen posted would be appreciated by a lot of the users. Also I added a few suggestions that I would appreciate. I will update this list as I think of other imo useful features.
Anyway I have to say too that octane is already a great Product that provides high Quality. This is true even more with the pricing in mind! Keep it up guys!
EDITED 06.19.2011:
-- White Balance in camera so you can correct color tints from e.g. tungsten lit HDRI´s (Would be no Problem to do this in post but due to 8bpc output you loose picture information)
-- Option to Link the F-Stop with the Aperture since this is a more real world behaviour (Right now Exposure, F-Stop and ISO are doing the same thing Is that right?)

-- Add a "Time Dependent" button to the renderer so the noise pattern gets distributed different for every frame.
To get rid of the issue in Animation where the noise seems static in front of the camera.
A different noise-distribution for every frame makes the animation render look much more like film.
This otherwise brilliant clip is a good example for the swimming noise effect:
