34s / 31s emulator new display

[ArneStolti]

Here comes a question from a not so experienced user: How (with which tool) can I alter / create a new skin for the emulators. I like the medium skin, but would like to change the 7 segment 'fonts' more similar to the real calculators. The *.xskin files look like a kind of xml graphics, but I could not open it directly with Inkscape.
