Tools such as Adobe Illustrator and InDesign work on vectors--would like to be able to import those into Indigo as vector-based images.

Only default UI component included in Indigo Studio are not cool to design mobile native application GUI.
For a designer of native mobile application, Indigo Studio is not used because too difficult about the product owner understanding when he don't see his prototype with native UI component rendering.

I want to be able to define conditions/rules based on, for example, user input that could conditionally change the state of my screens and/or control the flow for the user. This would imply remembering what users have put in and being able to reference it in the rules.

Would like to be able to jumpstart the development process from the prototype by getting HTML5 type code from it that we can then plug into the app being developed.

As above: let us choose external icons from disk repository (e.g. hard drive, network, etc.) of such way it releases a bigger wealth at prototyping.

I see two basic aspects of this:
1) Just saying "allow users to drag this" on elements/containers/groups, and they can move them around anywhere on screen just by doing that.
2) Define a "drop target" or more that when a draggable element is dropped on it results in a state change that I can define.

I'd like to prototype a sticky/pinned header, so that when users scroll down, I can have a header/menu stay stuck at the top of the browser viewport/window.

I'd like to be able to crop an image after putting it into Indigo.

Bonus points if it keeps the whole image so I could make copies and selectively crop to achieve a form of slicing.

I want to be able to easily import/use custom data from common formats like CSV, Excel, XML, HTML, JSON.

I can't get the storyboard slides to be full screen. I think the drawn scenarios are amazing but it's much easier to lead a presentation from a full screen view and then jump into the interactive prototypes off those slides.

Enable the possibility to set a gradient for a backgroud shape

I use Ubuntu for Android development so it would be nice to have Indigo on a Linux platform.

I really like what I've used of the product so far, but one big thing is missing - the ability to wireframe static text blocks. We really need a tool that produces greeking, or a lorem ipsum, or even the ability to just paste in paragraph text.

Add possibility to quickly duplicate selected object on canvas like in other apps with alt or control key.
Behaviour: Select object, press alt or ctrl and drag object on canvas
Axure - Ctrl +Drag
Fireworks - Alt + Drag

Frequently, my tables have controls in them--for example, inline editing cells would have a textbox in them. "Pick one of the table row" cells would have radio buttons in them. Select/Deselect all would have checkboxes in them.
Currently, I get around this by not using the table control, and just using rectangles for rows/cells, with the object or text I need layered on top of those rectangles.

For certain elements like boxes, text, buttons, etc. I would like to be able to add in drop shadows or inner shadows in order to give a bit more depth to the design.

I design applications for the Hebrew language, and we need support for RTL text and input.
