well, the advanced menu’s open up a variety of options, as you will soon find out once you explore some more (found in Edit Preferences ) , and the temp highlight selections allow for one less click with each op… which works hand in hand when your ops are bound to a hotkey setup.
Like say for instance you have bound extrude to a particular hotkey, now with temp highlight selection enabled when you mouse over the area v/e/f you wish to select, instead of having to click to select before doing the op, you would simply hit your extrude key when mouseover highlit… thus saving the extra click to select for each op… now if only they would enable doing multiple ops without having to click out first, then this workflow would double in speed… haha, sorry, I digress… 
anyway, glad to see you having some fun and learning this little gem of an app… good on you
and yes, axis is everthing once ya think about it, and since you have discovered such, I say right on 
have fun
