I like the "insert color" very much, it gives me many options to get a good colormanagement. I absolutely LOVE the fact, that in here, the document colors are displayed, so tedious seraching for hex values has an end.
However, I want to suggest to upgrade the colorpicker to be able picking colors outside of Rapid PHP. For me it makes no sense in picking a color inside of Rapid PHP, as very likely there are _no colors_ to pick that I would need.
So instead, like in phpDesigner, it would be cool to click on "Select ...", Rapid PHP minimize itself and one is able to pick any color available on the screen. Beeing a webpage, Photoshop, whatever. After picking, Rapid PHP restores itself and enters the value into the document at cursor position.
With that option, the "insert color" would be perfect.
