The on-screen keyboard already supports keyboard entry (i.e., when in the on-screen keyboard, just type if you want rather than clicking around on the keys). The only thing to keep in mind is that the DEL key is actually "delete" on a keyboard, not back-space. JFYI.

Thanks,

Jason

As far as the meters being pre or post-look, the biggest issue is that what you're seeing is all pixel shaders as far as the 3D LUT rendering is concerned, and this is what allows us to-do quite a bit of fancy stuff in real-time . . . the downside is that GPU's are meant to render *to* the screen, not recall data back into the computer, and as a result, that reverse path is REALLY slow and hogs a lot of CPU.

There is a histogram that reflects the actual effects of the look (i.e., the image "post-look" rather than the RAW data) when you're inside the IRIDAS color-correction screen, but as you can see there, it updates very slowly, and it pulls a lot of CPU (more than you would think necessary for something so "simple").

I guess in a year or so when resources and pipelines between GPU and CPU are much smoother this won't be so much of an issue, but for right now it is, especially on mobile platforms.
