I like the idea of promoting FEM-wb! Thats why i tried to watch your video and wanted to share it with colleagues.
There is only one problem
with your video. I think the "visual material" is a little bit faster then the sound or the other way around. When I jumped to the end of your youtube video I still here you speaking while I see you switching off the screencast-tool.
I tested i on firefox and chromium on two comps on ubuntu 16.04 and one mobile device and it is everywhere the same.
Can you please double-check?
Thanks in advance,
