Pro Nothing you don't need
Distraction and clutter free, not having too many options and features.
Con Not ideal for projects with overlapping audio
If you use the waveform to adjust timings for subtitles, adjusting one timing, if it comes into contact with the timing of another subtitle, will push the timings for the second timing so that they do not overlap. It's nice for clean cut situations, but not ideal when subtitles need to overlap.
Con Only creates / edits SRT files
Con Expensive for what you get
Considering excellent free options out there, the pricetag for this software is steep.
