I think as we are drawing closer to a presumed Flash client release date, it would be extremely helpful if somebody in the know could give us a list of the things that are probably NOT going to be possible in the new client.
* Custom interface files won't work - does this mean we get a map/info/output/input panel in the default 3.5 configuration? Map left, info/output right?
* Will any of the mouse functionality be restricted? Of course right-clicking is impossible (unless this has changed in Flash in the last few years), what about some of the more precise drag/drop methods?
* Will fps settings still work as they do currently? Will there be plateaus for fps (e.g. multiples of 5)?
Because we're (hopefully) so close to an early release, I'd really like to ensure my latest work is compatible right out of the gate, especially as it relates to complex GUI interaction with on-screen elements, and I'm sure many other folks are as well.
In addition, this information could be shared in a broader way (blog posts instead of a forum thread) to help set a baseline expectation and quell any potential disappointment from the reduced featureset.
Thanks for reading!
