The documentation is not up to date. It's missing new tags and changes made to old tags. Also a section that describes the deprecated tags.

Try to incorporate some of the great conversations that happened on the forums. Especially some of Theo's explanations.

That will allow the Mate community to participate and expand the documentation.

There is a problem when creating a new windown in air. The events that are bubbling up from the newly created window are not caught by the EventMap

Have the ability to inject or invoke, via global EventMaps, properties and methods on individual instances of a class. Right now you can only inject globally to all classes which isn't fine grained enough for many use cases.

in an effort to fully update the API docs, I would like to see examples relevant to the particular API in focus. Much like the Flex SDK API docs have

To go along with the other Mock Services, I would really like to see MockHTTPService.

Thanks!

It would be nice if it was made possible to integrate with the ChannelSet. You could handle login/logout requests. I have written an extension that gives an idea of what I mean:

Have the ability to access the instances with dot notation like:
cache.myId.someProperty
Where myid is an id that you choose when you create an instance using a Builder:
<ObjectBuilder cacheId="myId" generator="{myClass}" />

The only issue with this is that the word "cache" is already taken. It is used to define the type of cache, so we need to find a new world for that, such as "store".  Please add a comment if you have a better word and if you like the feature.

When splitting an app into pieces, it would be great if each piece could have two or more local event maps sharing the same cache (whithout having to use global cache).

Redesign the website to make it more easy to navigate and find things, like asdocs, Diagrams, downloads etc.
Make a wider design to improve the readability ( ex. forums are too narrow now).

I think using the forum is very hard. I am still not able to create an account. Maybe I am the only one, but I hope not.

Right now, you can't set inline invoker's method to a function passed in on the event (useful for callbacks).

It's fairly trivial to make it work. Here's a simple class that does it, even if it is a little bit of a hack.

An event dispatched from a component in an ApplicationControlBar is caught by the SystemManager and handled by the EventMap a second time.

Add a top level link from the main Mate site to this UserVoice forum to encourage more suggestions and participation from the general community.

Expand the Mate forums to include a General Flex/AS3 Forum as well. Mate users have a wealth of experience and knowledge of both Flex and AS3. A separate forum to field "General Flex/AS3" issues would help many I am sure.

Since in some applications it's need to use:
ServerConfig.getChannelSet("my-amf").login(username, password) for login i propouse ( and i created a first version ) of ChannelSetLoginInvoker tag
