Drupal 6 administration menu like the one on Drupal 7 I build a lot of sites, mostly on Drupal 7, so when I have to use Drupal 6 I am totally lost on the admin options, (even using the administrative menu bar).

Since I can't find any module for this issue, I am wondering if I should give it a try to build a module myself to rename and rearrange the admin menu items, but I am not sure, if this is even possible or if that will cause any path issues in modules later.
Why not building your own menu with the most used functions and show it only for you? I do this all the time for D6 and D7.
