I play on keyboard and I just have my keys changed from the traditional 1-= setup to using all the buttons around the wasd keys(q,e,r,f,g,c) then 1, 2, 3 for bars 1-3(Using shift and ctrl versions) Then I have 3 bars that use the NUM pad and the rest are Universal Bars that dont have keys. I learned this set up from playing The Old Republic(which has SOOO many skills that are all useful).

Because the game is built(in my mind) on a system where there is no real useless skill, I don't move anything around after I place that skill in the "correct" spot. Combos will be in order (q,e,f for me)and other skills may be on the same key on multiple bars(all cc skills on c, Shift+c, ctrl+c for example). So when I get synced, things never need to be moved and never get confusing. Skills are only ever in one place for me.
