When you select and object and hit G, it changes it location when you move your cursor.
If you hit G + X, you can move in only X axis.
And if you hit Alt+G, it says, “OK? Clear location?” and if you hit enter, it clears the objects location and puts it at global 0,0,0.
My suggestion is that , if I go,
Alt+G it says “OK? Clear location”, If I hit then X , it says “OK? Clear X Location?” and If i hit enter, it gives the object global X 0.
And if I go Alt+G+shift+X it says “OK? Clear Y,Z Location?”
This could be very useful to align objects in the 3d view. it doesn’t work like that at the moment for the Clear property kombo of alt+(G/R/S)
But when moving(G) or Rotating® or Scaling(S), you can exclude and include axis as you want.
Could be a impliment for 2.5 !
What do you think? is it necessary, how do you align objects ?
