In the thread it mentions svg.png as preferred. But the sketch files (home/user/.liqbase/sketches if memory serves) do not open up after renaming with .svg.png .svg or .png postfix. Also tried renaming to bmp jpg gif & tif with no luck. They look like vector files with co-ords inside. Also looked at the code for the liqriver.php page mentioned here and those are referring to svg files.

1- What format are these files?
2- What viewer can be used to open them outside liqbase?
3- What utility/app can be used on Windows to convert them to other formats?

Q. 3 is the crucial one, I know already:
Thanks.

P.S. If the toolbars on the right of the drawing screen could collapse to a small icon, and slide in/expand/re-appear if clicked, then all of the precious small screen space could be used.
