1.) For bigger projects, such as feature film editing, "nesting" becomes an important function. (Edit a project within a project, some call it compound clips) This is now already possible, but only by opening another instance of Vegas. Why not follow the example of FCP or others and introduce a Tab-Based functionality. Double-Clicking on such a compound clip would open that clip in another Tab of the Timeline. (which currently doesnt exist)
2.) Incoperate a software like Pluraleyes into Vegas, so audio-synching could be achieved easily without additional software.
3.) Add a De-Noising Filter to the Effects.
4.) Add a Section for Lower-Thirds Text Overlays with a lot of presets.
THANKS IN ADVANCE FOR CONSIDERING THOSE SUGGESTIONS.
