Nana has an interesting way to align the different widgets. I found this article:
Using colors offers a very clear vision of how widgets are distributed on the screen.
For simple designs it is fine, but for more complex ones it can be a real chaos.
Using nana-creator I recreate a complex window (about 40 widgets) of one of my programs in just 2 hours (without previous knowledge about nana-creator) which I think is very good.
But nana-creator is not up-to-date and unintuitive. I think that this program should be improved and updated. Having good tools surely attracts more users.
How do you do to design the windows?
