I was hoping to find your reply on the top.

As so many I started my 'vim-experience' by adding a lot of plugins, rc-settings, themes etc.

Finally I almost used as much time configuring, backing up my dot files and tweaking as I used on real actual programming.

I understand some settings are crucial (or may be nice), but I would recommend you use more time thinking and implementing your application.

I firmly believe that the KISS-principle (Keep it simple, stupid) is as important to IDE/Editors as it is writing software code.
