I hope I categorized this issue right (I do now know if such a suggestion
should be files as "feature" or as "enhancement"):

Let me describe the situation:
I write "1", "2" and "3" in three cells (in column "B") right below each other,
than I select (mark) those three cells. Then I drag the little
right box down for about 20 cells and get a nice list of
numbers from 1 to 23.

Then I start the same in the next column ("C"), type "1","2","3".
In M$excel, I would now just have to make a double-click on the little box 
to fill down all the cells until the first empty cell in Column "B" is reached.

In OO, I have to drag down manually again. 

This sounds not very important, but if you work with spreadheets containing
100 columns and thousands of rows, this Excel-feature becomes very important,
especially on fast computers, where you quickly miss the end of your table
in scrolling!

In Excel I can also just correct a wrong entry in the first cell of a column
and make a double-click on this little box and all equations in the cell below
get automatically updated until the bottom of the table.

Just a suggestion for 1.2 or 2.0
