I have used the beta now for a couple of wireframe projects . My usage pattern is to design the wireframe in Illustrator and then move the components to FC and work on button behaviors and states to create a "functional" wireframe. I am using a Vista machine with about 8 gigs of memory and a Dual Core processor. Here are some comments after a couple of weeks:
Import of Illustrator Files
-This works well for the most part although the editing of text is cumbersome and not intuitive. I ended up converting most of my text to vectors and simply cutting and pasting between the two applications.
-I have noticed that the text handling (kerning etc.) is often messed up when the files get imported into FC.
-My workflow tended to use Illustrator as a place to create elements and FC as a place to put functionality on them. My two files diverged pretty fast as a result. It would be really nice if I could export a state as an Illustrator file add to it or change layout and re-import.
-Importing Illustrator files with a lot of elements is a long process. It seems as if it would be good to allow the user to selectively identify layers at import time that could be optimized.
General Application Performance
-Running the application on my laptop was a waste of time, too slow.
-The current machine I have has ample resources but I would say that it bogs down and the application become very slow with a project that has 8-10 pages each with a lot of components.
-I have had several (2-3 times a day) times where the application simply vanishes without any error message and I need to start up again.
-Operations such as re-ordering layers are very slow and seem to take up a lot of processor and sometimes cause the application to fail.
-The initial feature set is very nice but there are a few things that I think will be essential very soon.
-Drag and Drop--a lot of applications need this. Even if you just let people define simple drag objects and drop zones. Without it many of my wireframes have a lot of notes explaining that this should be a drag object.
-Need to make it easy to make a component draggable for the end user such as a floating window.
-Many people have pointed out the need for some of the other components like dropdown etc. , I am sure these are in the works.
-As mentioned by others it would be nice to have the ability to put simple conditional logic on buttons. I assume in future releases I can do this in the code view. One thought to make this easy for non-coders is to provide people with a simple variable setting option for button and simple logic to check the variable. Often for wireframing this is sufficient to create interactive specifications.
-Need to have multiple select on the timeline. Dragging a bunch of elements individually to the 1 second mark makes me crazy.
-It would be nice to have context menus on items like Fade to easily set options (in/out, etc.)
-The layer control and the implications of grouping is somewhat hard to figure out. It would be nice to clarify the component/subcomponent/layer/group world for the user.
-The component preview never works for me
-The align option does not seem to work correctly. Trying to align 3 checkboxes resulted in a skewed alignment.
-The add object and add action options took a while to figure out but seemed usable once it was clear what the right order and usage was. Again being able to put conditional logic around which actions occur in the timeline would be useful.
