It's quite normal to use bleeding tabs to produce rows of dots between, for example, a title and a 
page number. In Writer they are called "fill characters" on the tab dialogue. 

I can't find any 
way to specify that the first and last "fill chararacters" should be replaced by white space, or 
any way to vertially align the "fill character" so they llook nice on the page. 

The work-round 
appears to be to put extra tabs in, and use "fill characters" only between the inner ones - but that 
means that the fill does not go all the way to the word on the left when the word lenghts vary 
significantly. 

Or I can put a single space at the end of each word on the left, and a tab before 
the number, but when using a proportional font the fill characters take thier "flow" from the 
words on the left, so the right hand edge is ragged. 

What is needed is a user option to specify 
minimum white space at each end of a run of fill charactes, and for them to align on the right, not the 
left. (in effect they want to be drawn backwards from the right!) 


By the way, I really like 
the ability to select different "fill characters", it's very smooth.
