There should have features of fading video and audio out. Markers are needed too. Ripple cut toggle on/off should be created too.
I used to edit in Edius and I see the features of fading video, audio out, ripple cut on/off toggle, clips markers, H.265 video compression for nowadays video smoothly played back on mobile devices, etc.

You can fade video and audio under Effects > Transitions

Generally, this is good for mobile and instant editing of short and small size formated video clips.
