Just because people who follow the vim google group want more ide features and python integration doesn't mean thats what most vim users want. Why don't they fix the obvious flaw, mouse integration? (I know, because it would be hard)
New features are voted on not by mailing list/Google group participants but by users who have donated at least €10 to the Ugandan charity that Bram sponsors via Vim development.
Also, I'm not sure in what sense mouse integration is "the obvious flaw", given that (A) it already exists if you use the GUI version, or in the terminal if your terminal supports mouse reporting (see :help mouse-using) and (B) most Vim users tend to actively avoid the mouse anyway.
Because many, many vim users (majority even?) are running vim on a headless *nix server with no display or display software, let alone a mouse. Anyway, there is already "set mouse=a", or use something like MacVim or another port of vim to graphical UI.
vi with mouse integration? They have had this for years. Download the source and grok my friend. You probably are running nvi and not vim. Also in either your terminal or x you can simply middle click your mouse if you need to mouse copy/paste. I recommend addressing in ex mode or using the vi visual mode commands to do it. If your really dependent on "drag/drop" gui style editing using ex proper will defeat that. In vim I'm sure a simple script would even bring it to the gui drag/drop concept to the editor by automating addressing from mouse selection. Though it would be slower for the end user and simply not provide the flow and control ed and vi/ex users have had for years.
