I’m evaluating which tool should I use to design my first mobile app. I know some very basic programming. If you don’t mind, I have two questions. I need a button (the name of a folder), that when touched on the plus sign it expands to show the list of the folders or files inside that folder. Now, if there is a folder inside that first folder, I would like it to do the same to show its contents too, so you can expand and collapse this folders/buttons touching the plus or minus sign. Do Indigo allow this? And the second question is. If this is possible, can you create a "set" with this folder/sub folder/files, and carry this "set" to different pages, with the functionality included? If not, do you have a suggestion of what prototyping tool may be able to do this?

Thanks!
