Using version 19.10.20
Part of the current work flow employs an automated process which creates an mlt file with blanks (candidates cuts) within the playlist that are not always perfect, so manual editing is required to move the blank start/stop edge to determine if the blank created is accurate, then undo or readjust the blank edge. To solve this, toggle the video preview window on videos with playlists containing blank lengths where the video preview will still display the video information when the play head is positioned within a blank space. Which brings the question of how does one observe, especially at low timeline zoom, if the playhead is resting on video or blank space if they both present the same way in the preview. This could be solved with shortcut keys; snap playhead to blank space start, and snap playhead to blank space end. Further, snap to blank edge would also allow for faster movement through the timeline. Even without the transparent/opaque blank space preview option, the snap to blank edge would mitigate excessive scrolling and/or timeline zoom/unzoom to find the next blank transition.
