Welcome to TVPaint Community forums !

- It would be nice to limit the export range to image mark sets. I was trying to export JUST my keys and breakdowns earlier and found it difficult to do so.

- Likewise, it would be cool to have some variable syntax in the file naming for export. So instead of having JUST (filename-001.png) and so on, you could have

%filename%-%frame-number%-%date%.png

or maybe,

%layername%-%frame-number%-of-%totalframes%.png

or

%layername%-%instance-number%.png

You see what I mean?

That's a nice idea, but then it should work only in the "clip : layer structure" tab.
