I am one of the project creators. This was a last year project in our company innovation week (http://piweek.com/) but it never become a large project because it is hard to make changes to the
Inkscape UI if you are not a developer.
So it was just a first draft to see if inkscape developers will like our ideas and we could help them to improve the UX/UI for future releases. It did not work and we just left the project.
Taiga design team here!
We are currently using two fonts:
- "Open Sans Condensed Light" for the titles.
- "Droid Sans" for the text.
Both are well known fonts and extremely used. We used Droid Sans in the text to make it easily readable. Titles are supposed to be readable, of course, but creative at the same time.
We added the issue to review with more testers if they see that problem as well. Thanks for the feedback :)
We have a couple issues with Safari.
One of them is related to the layout because Safari 7 has some issues with flexbox but it's already fixed in a branch and should be merged really soon.
We also have an issue with this JS problem with Safari when creating a new project that we are reviewing.
Thanks for your feedback. Everything should be working well with Firefox and Chrome if you want to create a project right now. :)
