Yes, I know, manual kerning has been available in Scribus for a long 
time. What I meant: there is no way to let the H&J algorithm 
automatically change letterspacing within limits that I can set.

You are right, but glyph extension is still being frowned upon by many 
people. I have no problem with it (as long as its limits are narrow). My 
point is the lack of use of letterspacing in H&J in Scribus.

To summarize: the examples in the above mentioned book convinced me, 
that you get the best result by including in the H&J automatic change of 
interword _and_ within-word spacing _and_ glyph extension. All of them 
with tight limits, that are not noticeable, but together give enough 
freedom to the H&J algorithm. I know including yet another variable 
complicates the algorithm even further, but please consider including it 
in the spirit of open source: by setting the limits the user could 
achieve any behaviour that she/he likes most. You, as a developer may 
"voice your opininon" by setting the _default_ limits of within-word 
spacing to 100%-100%, effectively disabling it.

Absolutely glad to hear that.

That's also very nice, but if native paragraph-oriented H&J is coming in 
Scribus, this is less important (at least to me).

By the way: very many thanks to the developers for this excellent tool. 
It is a _joy_ to work with Scribus, even with the development version 
with its bugs. I can put up with them, because to end product really 
looks the way I want. (If only H&J would be a bit better...)
