i don't recall any timeline capabilities were removed but i'm not sure what you mean by multiple timelines. to be sure, you can nest just as many timelines with all the flash versions from cs3 to cs 6.
Hello! how can I do that in CS6!??
how can you do what? nest timelines?
if so, click insert>new symbol>movieclip and create some graphics on the new movieclip timeline. drag that symbol from your library (window>library) to the main timeline.
Ah! ok, sorry, I should read it twice..
thanx, but I'm talking about having differents windows with a timeline each one.
In my studio we have few windows of the same project, but with diferent content, like "mouth symbol", "eyes symbol", etc... but in CS6 you have just one timeline window!!! so if multiple screens (like cintiq + iMac screen) you have the timeline far away the window you are editing!!
this is annoying!
in cs6 you can still drag the timeline outside the ide but, i don't see how you can view different timelines simultaneously.
how do you view different timelines concurrently in cs3?
Did you mean the Graphic Symbol Type? That hasn't been removed in CS6. Or did you mean something else, like Duplicate Window? If so, you need to be more specific. Note, I have no idea if Duplicate Window exists or not in CS6.
If you mean that you want the same fla open in many windows at the same time so that you can work on different parts/clips/symbols at the same time in the same source file, in CS6 you do that under menu Windows-> Duplicate windows. On PC also keyboard shortcut Ctrl+Alt+K.
I saw that in new Flash CC you can also find that by right clicking on the tab for an open fla.
