I think this kind of IDE would be very usefull during code-maintenance, especially when the code you maintain is written by you (which is often the case).
When developing new code, the bubble-concept could be too confusing, because it seems to hide the overall structure of the code.
But during maintenance, when hunting bugs, I often don't want to see the whole picture (and hence the whole complexity), but am much more interested in smaller sections of a program, and the relations between them. The bubble concept would really help.
Both "Middle" and "East" expose your ethnocentrism.
The middle east.
It's middle and it's east.
It basically takes you through all the basic(++) features of vim.
vimtutor made me really appreciate vim.
