[Kimchi-devel] GUI Prototyping Tool

Hi, today I was looking for an Open Source GUI Prototyping Tool. Harshal already used Pencil http://pencil.evolus.vn/ which is also the best I found. Pencil is an Open Source tool supporting multi platforms (Windows, Linux, Mac). It looks like development of Pencil stopped in 2013. I installed it and made some basic tests. In my opinion it is sufficient for visualizing general UI concepts in Kimchi/Ginmger but not for more. My recommendation is to use it for these aspects. What is your opinion? Do you know other tools? Kind regards Jan
