In the LyX word processor, which I recommend highly for technical writing, the on-screen layout of lists is very spread out. You can fix that easily by editing your stdlists.inc file, which you’ll find in /usr/share/lyx/layouts/stdlists.inc on linux, or in c:\Program Files\Lyx\Resources\layouts\stdlists.inc in Windows.
Just change ItemSep, TopSep, BottomSep, and ParSep to 0.0, and the bulleted lists become nice and compact.

It’s better to edit this in your preferences directory. Copy the stdlists.inc file to your Lyx preferences directory (in Linux: ~/.lyx/layouts) and edit it there.
