Make the curves editor more powerful

[GoogleCodeExporter]

I have been testing Delaboratory 0.6 beta (Windows xp profes sp3).

I think it would be very useful to make the curves editor more powerful.

In short:
- Add a shortcut to open it (e.g. Ctr+M as with Photoshop);
- Add an option do delete the point on the curve. 
With Gimp 2.7.4 you can press the button delete of your keyboard to achieve 
this. 
With Gimp to delete your point on the curve editor you can drag the point on 
the very upper-lower border.
Another option would be to add a button to "reset". In order to delete every 
change in the curve editor

BTW, I have noticed that when you press the button CTR of your keyboard 
(*while* you click on your image)the curve editor shows a vertical line.
In essence, it works as with Gimp with the color picker (while working with the 
curve editor).

As a consequence, I think it would be useful to have something like a "color 
picker" button in Delaboratory to make this option more visible.
Right now, this feature is "hidden" and it is difficult to discover it (unless 
you know other "similar" graphical softwares)

Currently it is possible to delete single point on curve with "x" key.
There also "a" and "z" keys to move it vertically.
You can also press "ctrl" to add curve point in each curves based on marker.

Please explain your idea with more details.

Sorry, I did not know about these shortcuts :-(
They are really useful. Thanks for pointing them out!

Just one more curiosity (*NOT* a request for a new feature).

I have read you have been greatly inspired by the book of Dan Margulis 
(Professional Photoshop).
I have been slowing reading it myself (the last version) :-)

Quite probably, my questions are a bit dumb (bear with me...)

Here they are:
1. Why did you not to choose to have 9 lines in the grid for the layer - curves 
editor (that is, an increment of 10% for every line)?
Is it possible to increase these lines on Delaboratory to get an increment of 
10% (and thus following Dan Margulis tutorials)?

2. Why did you not choose to put the darkness to the right in the layer - curve 
editor?
If you read the fifth version of Margulis' book you know what I mean (by 
reading Chapter 2; page 26, Figure 2.2).
The book is copyrighted, therefore and I can not attach here the image of that 
page.

Usually, with most software the Darkness is on the left (e.g. Gimp) but Dan 
Margulis suggests to set the Curve editor on Photoshop with the darness on the 
right.
Its point is that since CMYK AND GRAYSCALE have the rightness to the right, for 
consistency, is better to have every curve editor (RGB, LAB included) with the 
Darkness to the right

Please, don't take these two questions as a criticism for your work.
I don't want to lecture anyone...

It is really sheer curiosity since I admire a lot Delaboratory (and Margulis' 
book) :-)

Whilst it's good to have those keys, it would be far more intuitive to use 
standard cursor up and down, left and right keys. This is how it works in PS 
and seems to be pretty intiotive

Number of lines, background color, direction of curves and keys will be 
configurable when I introduce user configuration, it's not small task because 
it requires some kind of UI and soma kind of storage.

I hope this is a good suggestion

why not make the curve tool see-through, so that it doesn't obstruct the view 
of an image beneath.
