Hello Gimp Wizards,

This is my first post to this eminent forum. I'm a technical journalist 
working on a series of articles on freeware image editing software, for the 
Swedish monthly photo magazine FOTO.

Gimp seems to be the 'pièce de résistance' of free image manipulation programs 
and I'm already impressed by its capabilities.

However, being raised on Photoshop but a newbie with Gimp, I'm stumped by some 
of Gimp's functions. Please bear with me...

1) I can't seem to find any option for a continuous numerical readout of RGB 
and greyscale values as I move the cursor in the image!

I have discovered that I can use the Color Picker tool to get readouts if I 
click somewhere. BUT, if I invoke a function like Color Correction, the Color 
Picker window is disabled and no help at all for checking stuff like clipping 
channels or colour casts of areas that should be neutral.

>From Photoshop I'm used to always having readouts available in the Info 
palette. In Gimp, it seems that though I get all kinds of positional data in 
the lower left image frame corner, there's no color data readout option.

2) The Decompose to... and Compose to... functions are intriguing and 
potentially useful, BUT so far, I haven't been able to, say, Decompose an RGB 
image to LAB (for sharpening just the L channel or for adjusting gamma without 
colour saturation buildup) AND then Compose the layered image back to RGB!

When I try, I get truly weird colours and I get the impression that Decompose 
to... and Compose to... don't work in a complementary or transparent manner. 
This makes me wonder what these functions are meant for. 

So, again, there might be something I'm just missing, being weaned on 
Photoshop, and if anybody could set me on the right track, I'd be most
