Effects
I believe that the effects menu is tedious for sound design workflow. I would suggest that you simplify effects use by making a tool button menu adjacent right click menu. The tool button menu should be able to cycle through effects by category via mouse scroll wheel, each category with relatable effects. Most commonly used effects can be in a menu that’s not affected by mouse scroll but always available. So three menus should be shown when clicking the right mouse button, the default menu, effects by category and main effects. I would suggest in main effects the amplify buttons up and down should be available for ease of use and fade in and fade out. so the workflow will be select region of audio, right click, press button of desired effect. there should be good defaults so there is less tedious tweaking in the tool properties dialogues. By default clicking on effect button will use that effects defaults and apply to selected audio.
