The contextual menu for a sound in the timeline, offers a lot of possibilities but they are quite useless (or you need them as the beginning of a post-production work, for conforming).
I would be very very happy, if the audiosuite menu just be added in that contextual menu. It seems very natural that when you work on a sound, the mouse pointer is near that sound and if you decide an audiosuite treatment it would be much more easier to load the plug in from the time line without having to go to the top menu. I feel quite annoying to have to go to that menu at the top of the screen each time.
the best option would be to have, like you can do for the insert plug-ins, the possibility to have a few plug-ins, like denoise or plugs that you use a lot as audiosuite, that appears directly in that contextual menu.
