I'm not sure, I still see this dismissiveness. Hell, open any HN thread about design and see how many will ask what designers even do all day, or talk about them as if they're "less than" developers.
I can proudly say that our team not only cares about design, but has put Design and User Experience at the center of the product development. We are designing an improved interface, with special accessible approach, and also having special care about the way space is used (information density like you said). Likewise, we know this is a critical point in terms of a project management tool.
I'm really looking forward to sharing more advances! For now, we are sharing some of them on Taiga community (https://community.taiga.io/), please feel free to post your thoughts, ideas, and feedback.
I'm a strong proponent of open source and highly usable tools for critical project infrastructure.
I really wanted Taiga to work for us, and I look forward to revisiting it in the new version.
But I think the real issue is that UX is more work than most developers expect, and especially to iterate over time.
UX mistakes (or imperfections) are visible for all to see, and correctness is sometimes subjective. Imagine if all of our users were able, qualified, and effectively required to evaluate source code! We do some lazy/misguided/opinionated stuff too, sometimes! :)
I didn't mean to dis Taiga above. It's thoroughly functional, if not quite right for the users I was testing with. I tried Taiga because I know the other options mostly suck, and my next-step-test is not definitively better!
