I would love to see a possibility to insert the current clock / time (or even date) and a countdown timer.
This could be useful on several projects (New year, sport activities, etc.)

It would be nice to add a default setting in the preferences to set the duration of clips.
When importing multiple pictures which need to be shown like a slideshow it would be nice to have a default setting for the duration or an option to select them all and set a duration once for all the clips.
