Add a roadmap

[vmadman]

In the README, you say that you suck at CSS and don't know jQuery, but despite all of that your editor seems pretty nice. Once I read "PLEASE CONTRIBUTE" I started trying to figure out what you needed, but could not.

I may or may not have time to contribute, but if you could provide a roadmap, or create a bunch of issues with some cleverly devised labels, I think the odds of getting help will increase.

Also, good work.

That's a good question. I don't remember what I need or what the roadmap should be. I wrote it for this

The inspiration is of course the Photoshop one

Off the top of my head:

• The ramp at the top should draw a checkboard behind so you can see alpha

• I'd like the color editor to seem more integrated.

  Photoshop works by having the color editor in a different window. I'm not sure which is better.

• Option to separate alpha?

  Photoshop has the alpha gradient separate from color gradient. I'm not sure how to implement that in terms of the data you get back though. The easiest way would be to generate a stop at the union of both gradients. If that makes sense. In other words if you have

  V                  V              V    : color stops
  -----------------------------------
         ^                 ^           : alpha stops

  Then you'd get back a gradient with 5 stops.

• Should it support the biasing (not sure what photoshop calls that).

  In Photoshop there's a tiny diamond between each stop which you can use to kind of set a midpoint and make the gradient concentrate on one side or the other. Unfortunately I know of no way to actually support that feature except to generate lots of stops.

• I'd like it to be prettier and more functional
  • Give the stops something more than just a box. A box with a pointer.
  • Figure out what to do with the mostly empty space right of the color picker
  • Highlight which stop is selected
  • Select more than one color stop at a time (shift click)
  • Figure out why it sometimes adds an extra color stop at the beginning (bug)
  • Have an optional gradient collection (like Photoshop)
  • Support more that just linear gradients (radial for example)
  • Add in the offset and scale features of Photoshop.
• Or you could just ask this guy to open source his editor and then wrap it in a jquery control :P
