I recently submitted a similar enhancement for LibreOffice Writer.
When formatting cells, it is not possible to choose a dotted line. One can only choose a dashed line.
I--and, I think, many other users--would appreciate if there was the possibility to insert borders which consist out of really round dots.
MS Excel offers the possibility to use dotted lines. But when you export the file as a pdf, the line is not dotted anymore, but drawn through. This is just a hint to an error which is best be avoided. :-)
Again, I didn't think that a graphical example is necessary here. I you are of a different opinion, let me know.
Reasonable enhancement request. Setting to NEW.
@Tobias - enhancements are implemented by volunteers, thus I'm just confirming it's a valid request, not guaranteeing it'll ever be implemented. Good chance this one never is (a volunteer would have to find it interesting enough to give a lot of time to implement it). But, you never know :)
