Hello Hein, you're probably aware of the Options -> Crossfades settings that 
can do this for you.

Yes, the time-constrained copy-drag seems to be gone or we have borked 
windowmanagers, whatever. You can work around this with "Snap To" settings. 
These are in the two popup menus that default to "Normal" (= Snap Mode) 
and "None" (= Snap to what). Like
1. Drag the blue edit cursor to your starting split.
2. Right-click -> Split
3. Set "Snap To" to "Edit cursor"
4. Ctrl-click to copy-drag the partial region to another track (it'll snap to 
the edit cursor)
5. Set "Snap To" to "None" and drag-adjust the end of the region to your needs 
or have a second split - same effect.

A new playlist will be empty or carry the same regions (with playlist -> new 
copy). So this doesn't help.

Punching over is fine. I _think_ the disk cacheing in playback pulls in every 
layer so huge amounts of punches on top of each other could become a problem.

Every ardour session needs and has an end marker. Zoom out or look in 
Windows -> Locations which gives you draggable clocks to move the end marker 
closer to your end. Oh, start and end markers show up in the "Location 
Markers" ruler which could be invisible. Right-click in the ruler head to get

The export window has a check-outputs part where you need to click-check the 
(default) master outputs or set "Specific tracks ...".
"Sometimes" empty though is a tad irritating.
