...add pasting voice overs, text align tool and basic grid snapping
When doing software tutorials, you record various snippets, then put them together with a short title and end sequence - but one can then not add voice-overs in the exact places one wants for the duration one wants. Scripted recordings are very cumbersome. Much easier to paste multiple video snippets together and later add voice-overs from external sources like pro speakers, etc.
When using text overlays, one can not align the text left, right or centre and, even worse, position the text boxes consistently; without any grid snapping, they just jump around, unless one puts the text in the default centre location as a single line.
