I liked that entire project — including targets and build steps — was in the tree view on the left.

Now tree view has been limited to be a file browser. Targets and build steps are now hidden deeper in settings windows and tabs.

To me old way was simpler and felt more elegant.

I'm not fond of "mystery meat navigation" — tabs have icons instead of text labels. I'm sure I'll learn that quickly, but it makes learning curve higher and on first impression UI looks more overwhelming.
